-# Elevation Quality of Life Improvements
-
-## Abstract
-
-For a long time, we've been researching adding support to the Windows Terminal
-for running both unelevated and elevated (admin) tabs side-by-side, in the same
-window. However, after much research, we've determined that there isn't a safe
-way to do this without opening the Terminal up as a potential
-escalation-of-privilege vector.
-
-Instead, we'll be adding a number of features to the Terminal to improve the
-user experience of working in elevated scenarios. These improvements include:
-
-* A visible indicator that the Terminal window is elevated ([#1939])
-* Configuring the Terminal to always run elevated ([#632])
-* Configuring a specific profile to always open elevated ([#632])
-* Allowing new tabs, panes to be opened elevated directly from an unelevated
-  window
-* Dynamic profile appearance that changes depending on if the Terminal is
-  elevated or not. ([#1939], [#8311])
-
-## Background
-
-_This section was originally authored in the [Process Model 2.0 Spec]. Please
-refer to it there for its original context._
-
-Let's presume that you're a user who wants to be able to open an elevated tab
-within an otherwise unelevated Terminal window. We call this scenario "mixed
-elevation" - the tabs within the Terminal can be running either unelevated _or_
-elevated client applications.
-
-It wouldn't be terribly difficult for the unelevated Terminal to request the
-permission of the user to spawn an elevated client application. The user would
-see a UAC prompt, they'd accept, and then they'd be able to have an elevated
-shell alongside their unelevated tabs.
-
-However, this creates an escalation of privilege vector. Now, there's an
-unelevated window which is connected directly to an elevated process. At this
-point, **any other unelevated application could send input to the Terminal's
-`HWND`**. This would make it possible for another unelevated process to "drive"
-the Terminal window, and send commands to the elevated client application.
-
-It was initially theorized that the window/content model architecture would also
-help enable "mixed elevation". With mixed elevation, tabs could run at different
-integrity levels within the same terminal window. However, after investigation
-and research, it has become apparent that this scenario is not possible to do
-safely after all. There are numerous technical difficulties involved, and each
-with their own security risks. At the end of the day, the team wouldn't be
-comfortable shipping a mixed-elevation solution, because there's simply no way
-for us to be confident that we haven't introduced an escalation-of-privilege
-vector utilizing the Terminal. No matter how small the attack surface might be,
-we wouldn't be confident that there are _no_ vectors for an attack.
-
-Some things we considered during this investigation:
-
-* If a user requests a new elevated tab from an otherwise unelevated window, we
-  could use UAC to create a new, elevated window process, and "move" all the
-  current tabs to that window process, as well as the new elevated client. Now,
-  the window process would be elevated, preventing it from input injection, and
-  it would still contains all the previously existing tabs. The original window
-  process could now be discarded, as the new elevated window process will
-  pretend to be the original window.
-  - However, it is unfortunately not possible with COM to have an elevated
-    client attach to an unelevated server that's registered at runtime. Even in
-    a packaged environment, the OS will reject the attempt to `CoCreateInstance`
-    the content process object. this will prevent elevated windows from
-    re-connecting to unelevated client processes.
-  - We could theoretically build an RPC tunnel between content and window
-    processes, and use the RPC connection to marshal the content process to the
-    elevated window. However, then _we_ would need to be responsible for
-    securing access the the RPC endpoint, and we feel even less confident doing
-    that.
-  - Attempts were also made to use a window-broker-content architecture, with
-    the broker process having a static CLSID in the registry, and having the
-    window and content processes at mixed elevation levels `CoCreateInstance`
-    that broker. This however _also_ did not work across elevation levels. This
-    may be due to a lack of Packaged COM support for mixed elevation levels.
-
-    It's also possible that the author forgot that packaged WinRT doesn't play
-    nicely with creating objects in an elevated context. The Terminal has
-    previously needed to manually manifest all its classes in a SxS manifest for
-    Unpackaged WinRT to allow the classes to be activated, rather than relying
-    on the packaged catalog. It's theoretically possible that doing that would
-    have allowed the broker to be activated across integrity levels.
-
-    Even if this approach did end up working, we would still need to be
-    responsible for securing the elevated windows so that an unelevated attacker
-    couldn't hijack a content process and trigger unexpected code in the window
-    process. We didn't feel confident that we could properly secure this channel
-    either.
-
-We also considered allowing mixed content in windows that were _originally_
-elevated. If the window is already elevated, then it can launch new unelevated
-processes. We could allow elevated windows to still create unelevated
-connections. However, we'd want to indicate per-pane what the elevation state
-of each connection is. The user would then need to keep track themselves of
-which terminal instances are elevated, and which are not.
-
-This also marks a departure from the current behavior, where everything in an
-elevated window would be elevated by default. The user would need to specify for
-each thing in the elevated window that they'd want to create it elevated. Or the
-Terminal would need to provide some setting like
-`"autoElevateEverythingInAnElevatedWindow"`.
-
-We cannot support mixed elevation when starting in a unelevated window.
-Therefore, it doesn't make a lot of UX sense to support it in the other
-direction. It's a cleaner UX story to just have everything in a single window at
-the same elevation level.
-
-## Solution Design
-
-Instead of supporting mixed elevation in the same window, we'll introduce the
-following features to the Terminal. These are meant as a way of improving the
-quality of life for users who work in mixed-elevation (or even just elevated)
-environments.
-
-### Visible indicator for elevated windows
-
-As requested in [#1939], it would be nice if it was easy to visibly identify if
-a Terminal window was elevated or not.
-
-One easy way of doing this is by adding a simple UAC shield to the left of the
-tabs for elevated windows. This shield could be configured by the theme (see
-[#3327]). We could provide the following states:
-* Colored (the default)
-* Monochrome
-* Hidden, to hide the shield even on elevated windows. This is the current
-  behavior.
-
-![UAC-shield-in-titlebar](UAC-shield-in-titlebar.png)
-_figure 1: a monochrome UAC shield in the titlebar of the window, courtesy of @mdtauk_
-
-We could also simplify this to only allow a boolean true/false for displaying
-the shield. As we do often with other enums, we could define `true` to be the
-same as the default appearance, and `false` to be the hidden option. As always,
-the development of the Terminal is an iterative process, where we can
-incrementally improve from no setting, to a boolean setting, to a enum-backed
-one.
-
-### Configuring a profile to always run elevated
-
-Oftentimes, users might have a particular tool chain that only works when
-running elevated. In these scenarios, it would be convenient for the user to be
-able to identify that the profile should _always_ run elevated. That way, they
-could open the profile from the dropdown menu of an otherwise unelevated window
-and have the elevated window open with the profile automatically.
-
-We'll be adding the `"elevate": true|false` setting as a per-profile setting,
-with a default value of `false`. When set to `true`, we'll try to auto-elevate
-the profile whenever it's launched. We'll check to see if this window is
-elevated before creating the connection for this profile. If the window is not
-elevated, then we'll create a new window with the requested elevation level to
-handle the new connection.
-
-`"elevate": false` will do nothing. If the window is already elevated, then the
-profile won't open an un-elevated window.
-
-If the user tries to open an `"elevate": true` profile in a window that's
-already elevated, then a new tab/split will open in the existing window, rather
-than spawning an additional elevated window.
-
-There are three situations where we're creating new terminal instances: new
-tabs, new splits, and new windows. Currently, these are all actions that are
-also exposed in the `wt` commandline as subcommands. We can convert from the
-commandline arguments into these actions already. Therefore, it shouldn't be too
-challenging to convert these actions back into the equal commandline arguments.
-
-For the following examples, let's assume the user is currently in an unelevated
-Terminal window.
-
-When the user tries to create a new elevated **tab**, we'll need to create a new
-process, elevated, with the following commandline:
-
-```
-wt new-tab [args...]
-```
-
-When we create this new `wt` instance, it will obey the glomming rules as
-specified in [Session Management Spec]. It might end up glomming to another
-existing window at that elevation level, or possibly create its own window.
-
-Similarly, for a new elevated **window**, we can make sure to pass the `-w new`
-arguments to `wt`. These parameters indicate that we definitely want this
-command to run in a new window, regardless of the current glomming settings.
-
-```
-wt -w new new-tab [args...]
-```
-
-However, creating a new **pane** is a little trickier. Invoking the `wt
-split-pane [args...]` is straightforward enough.
-
-<!-- Discussion notes follow:
-If the current window doesn't have the same elevation level as the
-requested profile, do we always want to just create a new split? If the command
-ends up glomming to an existing window, does that even make sense? That invoking
-an elevated split in an unelevated window would end up splitting the elevated
-window? It's very possible that the user wanted a split in the tab they're
-currently in, in the unelevated window, but they don't want a split in the
-elevated window.
-
-What if there's not space in the elevated window to create the split (but there
-would be in the current window)? That would sure make it seem like nothing
-happened, silently.
-
-We could alternatively have cross-elevation splits default to always opening a
-new tab. That might mitigate some of the odd behaviors. Until we actually have
-support for running commands in existing windows, we'll always need to make a
-new window when running elevated. We'll need to make the new window for new tabs
-and splits, because there's no way to invoke another existing window.
-
-A third proposal is to pop a warning dialog at the user when they try to open an
-elevated split from and unelevated window. This dialog could be something like
-
-> What you requested couldn't be completed. Do you want to:
-> A. Make me a new tab instead.
-> B. Forget it and cancel. I'll go fix my config.
-
-I'm certainly leaning towards proposal 2 - always create a new tab. This is how
-it's implemented in [#8514]. In that PR, this seems to work sensibly.
--->
-
-After discussing with the team, we have decided that the most sensible approach
-for handling a cross-elevation `split-pane` is to just create a new tab in the
-elevated window. The user can always re-attach the pane as a split with the
-`move-pane` command once the new pane in the elevated window.
-
-#### Configure the Terminal to _always_ run elevated
-
-`elevate` is a per-profile property, not a global property. If a user
-wants to always have all instances of the Terminal run elevated, they
-could set `"elevate": true` in their profile defaults. That would cause _all_
-profiles they launch to always spawn as elevated windows.
-
-#### `elevate` in Actions
-
-Additionally, we'll add the `elevate` property to the `NewTerminalArgs` used in
-the `newTab`, `splitPane`, and `newWindow` actions. This is similar to how other
-properties of profiles can be overridden at launch time. This will allow
-windows, tabs and panes to all be created specifically as elevated windows.
-
-In the `NewTerminalArgs`, `elevate` will be an optional boolean, with the
-following behavior:
-* `null` (_default_): Don't modify the `elevate` property for this profile
-* `true`: This launch should act like the profile had `"elevate": true` in its
-  properties.
-* `false`: This launch should act like the profile had `"elevate": false` in its
-  properties.
-
-We'll also add an iterable command for opening a profile in an
-elevated tab, with the following json:
-
-```jsonc
-{
-    // New elevated tab...
-    "name": { "key": "NewElevatedTabParentCommandName", "icon": "UAC-Shield.png" },
-    "commands": [
-        {
-            "iterateOn": "profiles",
-            "icon": "${profile.icon}",
-            "name": "${profile.name}",
-            "command": { "action": "newTab", "profile": "${profile.name}", "elevated": true }
-        }
-    ]
-},
-```
-
-#### Elevation from the dropdown
-
-Currently, the new tab dropdown supports opening a new pane by
-<kbd>Alt+click</kbd>ing on a profile. We could similarly add support to open a
-tab elevated with <kbd>Ctrl+click</kbd>. This is similar to the behavior of the
-Windows taskbar. It supports creating an elevated instance of a program by
-<kbd>Ctrl+click</kbd>ing on entries as well.
-
-## Implementation Details
-
-### Starting an elevated process from an unelevated process
-
-It seems that we're able to create an elevated process by passing the `"runas"`
-verb to
-[`ShellExecute`](https://docs.microsoft.com/en-us/windows/win32/api/shellapi/nf-shellapi-shellexecutea).
-So we could use something like
-
-```c++
-ShellExecute(nullptr,
-             L"runas",
-             L"wt.exe",
-             L"-w new new-tab [args...]",
-             nullptr,
-             SW_SHOWNORMAL);
-```
-
-This will ask the shell to perform a UAC prompt before spawning `wt.exe` as an
-elevated process.
-

-## Potential Issues
-
-<table>
-<tr>
-<td><strong>Accessibility</strong></td>
-<td>
-
-The set of changes proposed here are not expected to introduce any new
-accessibility issues. Users can already create elevated Terminal windows. Making
-it easier to create these windows doesn't really change our accessibility story.
-
-</td>
-</tr>
-<tr>
-<td><strong>Security</strong></td>
-<td>
-
-We won't be doing anything especially unique, so there aren't expected to be any
-substantial security risks associated with these changes. Users can already
-create elevated Terminal windows, so we're not really introducing any new
-functionality, from a security perspective.
-
-We're relying on the inherent security of the `runas` verb of `ShellExecute` to
-prevent any sort of unexpected escalation-of-privilege.
-
-<hr>
-
-One security concern is the fact that the `settings.json` file is currently a
-totally unsecured file. It's completely writable by any medium-IL process. That
-means it's totally possible for a malicious program to change the file. The
-malicious program could find a user's "Elevated PowerShell" profile, and change
-the commandline to `malicious.exe`. The user might then think that their
-"Elevated PowerShell" will run `powershell.exe` elevated, but will actually
-auto-elevate this attacker.
-
-If all we expose to the user is the name of the profile in the UAC dialog, then
-there's no way for the user to be sure that the program that's about to be
-launched is actually what they expect.
-
-To help mitigate this, we should _always_ pass the evaluated `commandline` as a
-part of the call to `ShellExecute`. the arguments that are passed to
-`ShellExecute` are visible to the user, though they need to click the "More
-Details" dropdown to reveal them.
-
-We will need to mitigate this vulnerability regardless of adding support for the
-auto-elevation of individual terminal tabs/panes. If a user is launching the
-Terminal elevated (i.e. from the Win+X menu in Windows 11), then it's possible
-for a malicious program to overwrite the `commandline` of their default profile.
-The user may now unknowingly invoke this malicious program while thinking they
-are simply launching the Terminal.
-
-To deal with this more broadly, we will display a dialog within the Terminal
-window before creating **any** elevated terminal instance. In that dialog, we'll
-display the commandline that will be executed, so the user can very easily
-confirm the commandline.
-
-This will need to happen for all elevated terminal instances. For an elevated
-Windows Terminal window, this means _all_ connections made by the Terminal.
-Every time the user opens a new profile or a new commandline in a pane, we'll
-need to prompt them first to confirm the commandline. This dialog within the
-elevated window will also prevent an attacker from editing the `settings.json`
-file while the user already has an elevated Terminal window open and hijacking a
-profile.
-
-The dialog options will certainly be annoying to users who don't want to be
-taken out of their flow to confirm the commandline that they wish to launch.
-There's precedent for a similar warning being implemented by VSCode, with their
-[Workspace Trust] feature. They too faced a similar backlash when the feature
-first shipped. However, in light of recent global cybersecurity attacks, this is
-seen as an acceptable UX degradation in the name of application trust. We don't
-want to provide an avenue that's too easy to abuse.
-
-When the user confirms the commandline of this profile as something safe to run,
-we'll add it to an elevated-only version of `state.json`. (see [#7972] for more
-details). This elevated version of the file will only be accessible by the
-elevated Terminal, so an attacker cannot hijack the contents of the file. This
-will help mitigate the UX discomfort caused by prompting on every commandline
-launched. This should mean that the discomfort is only limited to the first
-elevated launch of a particular profile. Subsequent launches (without modifying
-the `commandline`) will work as they always have.
-
-The dialog for confirming these commandlines should have a link to the docs for
-"Learn more...". Transparency in the face of this dialog should
-mitigate some dissatisfaction.
-
-The dialog will _not_ appear if the user does not have a split token - if the
-user's PC does not have UAC enabled, then they're _already_ running as an
-Administrator. Everything they do is elevated, so they shouldn't be prompted in
-this way.
-
-The Settings UI should also expose a way of viewing and removing these cached
-entries. This page should only be populated in the elevated version of the
-Terminal.

-### Centennial Applications
-
-In the past, we've had a notoriously rough time with the Centennial app
-infrastructure and running the Terminal elevated. Notably, we've had to list all
-our WinRT classes in our SxS manifest so they could be activated using
-unpackaged WinRT while running elevated. Additionally, there are plenty of
-issues running the Terminal in an "over the shoulder" elevation (OTS) scenario.
-
-Specifically, we're concerned with the following scenario:
-  * the current user account has the Terminal installed,
-  * but they aren't an Administrator,
-  * the Administrator account doesn't have the Terminal installed.
-
-In that scenario, the user can run into issues launching the Terminal in an
-elevated context (even after entering the Admin's credentials in the UAC
-prompt).
-
-This spec proposes no new mitigations for dealing with these issues. It may in
-fact make them more prevalent, by making elevated contexts more easily
-accessible.
-
-Unfortunately, these issues are OS bugs that are largely out of our own control.
-We will continue to apply pressure to the centennial app team internally as we
-encounter these issues. They are are team best equipped to resolve these issues.
-
-### Default Terminal & auto-elevation
-
-In the future, when we support setting the Terminal as the "default terminal
-emulator" on Windows. When that lands, we will use the `profiles.defaults`
-settings to create the tab where we'll be hosting the commandline client. If the user has
-`"elevate": true` in their `profiles.defaults`, we'd usually try to
-auto-elevate the profile. In this scenario, however, we can't do that. The
-Terminal is being invoked on behalf of the client app launching, instead of the
-Terminal invoking the client application.
-
-**2021-08-17 edit**: Now that "defterm" has shipped, we're a little more aware
-of some of the limitations with packaged COM and elevation boundaries. Defterm
-cannot be used with elevated processes _at all_ currently (see [#10276]). When
-an elevated commandline application is launched, it will always just appear in
-`conhost.exe`. Furthermore, An unelevated peasant can't communicate with an
-elevated monarch so we can't toss the connection to the elevated monarch and
-have them handle it.
-
-The simplest solution here is to just _always_ ignore the `elevate` property for
-incoming defterm connections. This is not an ideal solution, and one that we're
-willing to revisit if/when [#10276] is ever fixed.
-
-### Elevation on OneCore SKUs
-
-This spec proposes using `ShellExecute` to elevate the Terminal window. However,
-not all Windows SKUs have support for `ShellExecute`. Notably, the non-Desktop
-SKUs, which are often referred to as "OneCore" SKUs. On these platforms, we
-won't be able to use `ShellExecute` to elevate the Terminal. There might not
-even be the concept of multiple elevation levels, or different users, depending
-on the SKU.
-
-Fortunately, this is a mostly hypothetical concern for the moment. Desktop is
-the only publicly supported SKU for the Terminal currently. If the Terminal ever
-does become available on those SKUs, we can use these proposals as mitigations.
-
-* If elevation is supported, there must be some other way of elevating a
-  process. We could always use that mechanism instead.
-* If elevation isn't supported (I'm thinking 10X is one of these), then we could
-  instead display a warning dialog whenever a user tries to open an elevated
-  profile.
-  - We could take the warning a step further. We could add another settings
-    validation step. This would warn the user if they try to mark any profiles
-    or actions as `"elevate":true`
-
-## Future considerations
-
-* If we wanted to go even further down the visual differentiation route, we
-  could consider allowing the user to set an entirely different theme ([#3327])
-  based on the elevation state. Something like `elevatedTheme`, to pick another
-  theme from the set of themes. This would allow them to force elevated windows
-  to have a red titlebar, for example.
-* Over the course of discussion concerning appearance objects ([#8345]), it
-  became clear that having separate "elevated" appearances defined for
-  `profile`s was overly complicated. This is left as a consideration for a
-  possible future extension that could handle this scenario in a cleaner way.
-* Similarly, we're going to leave [#3637] "different profiles when elevated vs
-  unelevated" for the future. This also plays into the design of "configure the
-  new tab dropdown" ([#1571]), and reconciling those two designs is out-of-scope
-  for this particular release.
-* Tangentially, we may want to have a separate Terminal icon we ship with the
-  UAC shield present on it. This would be especially useful for the tray icon.
-  Since there will be different tray icon instances for elevated and unelevated
-  windows, having unique icons may help users identify which is which.
-
-### De-elevating a Terminal
-
-the original version of this spec proposed that `"elevated":false` from an
-elevated Terminal window should create a new unelevated Terminal instance. The
-mechanism for doing this is described in [The Old New Thing: How can I launch an
-unelevated process from my elevated process, redux].
-
-This works well when the Terminal is running unpackaged. However, de-elevating a
-process does not play well with packaged centennial applications. When asking
-the OS to run the packaged application from an elevated context, the system will
-still create the child process _elevated_. This means the packaged version of
-the Terminal won't be able to create a new unelevated Terminal instance.
-
-From an internal mail thread:
-
-> App model intercepts the `CreateProcess` call and redirects it to a COM
-> service. The parent of a packaged app is not the launching app, it’s some COM
-> service. So none of the parent process nonsense will work because the
-> parameters you passed to `CreateProcess` aren’t being used to create the
-> process.
-
-If this is fixed in the future, we could theoretically re-introduce de-elevating
-a profile. The original spec proposed a `"elevated": bool?` setting, with the
-following behaviors:
-* `null` (_default_): Don't modify the elevation level when running this profile
-* `true`: If the current window is unelevated, try to create a new elevated
-  window to host this connection.
-* `false`: If the current window is elevated, try to create a new unelevated
-  window to host this connection.
-
-We could always re-introduce this setting, to supercede `elevate`.
-
-### Change profile appearance for elevated windows
-
-In [#3062] and [#8345], we're planning on allowing users to set different
-appearances for a profile whether it's focused or not. We could do similar thing
-to enable a profile to have a different appearance when elevated. In the
-simplest case, this could allow the user to set `"background": "#ff0000"`. This
-would make a profile always appear to have a red background when in an elevated
-window.
-
-The more specific details of this implementation are left to the spec
-[Configuration object for profiles].
-
-In discussion of that spec, we decided that it would be far too complicated to
-try and overload the `unfocusedAppearance` machinery for differentiating between
-elevated and unelevated versions of the same profile. Already, that would lead
-to 4 states: [`appearance`, `unfocusedAppearance`, `elevatedAppearance`,
-`elevatedUnfocusedAppearance`]. This would lead to a combinatorial explosion if
-we decided in the future that there should also be other states for a profile.
-
-This particular QoL improvement is currently being left as a future
-consideration, should someone come up with a clever way of defining
-elevated-specific settings.
-
-<!--
-Brainstorming notes for future readers:
-
-You could have a profile that layers on an existing profile, with elevated-specific settings:
-
-{
-  "name": "foo",
-  "background": "#0000ff",
-  "commandline": "cmd.exe /k echo I am unelevated"
-},
-{
-  "inheritsFrom": "foo",
-  "background": "#ff0000",
-  "elevate": true,
-  "commandline": "cmd.exe /k echo I am ELEVATED"
-}

-# Actions Page
-
-## Abstract
-
-We need to represent actions inside the settings UI. This spec goes through the possible use cases and reasoning for including specific features for actions inside the settings UI.
-
-## Background
-
-### Inspiration
-
-It would be ideal if we could get the settings UI to have parity with the JSON file. This will take some design work if we want every feature possible in relation to actions. There is also the option of not having parity with the JSON file in order to present a simpler UX.
-
-### User Stories
-
-All of these features are possible with the JSON file. This spec will go into discussion of which (possibly all) of these user stories need to be handled by the settings UI.
-
-- Add key bindings to an action that does not already have keys assigned
-- Edit key bindings for an action
-- Remove key bindings from an action
-- Add multiple key bindings for the same action
-- Create an iterable action
-- Create a nested action
-- Choose which actions appear inside the command palette
-- See all possible actions, regardless of keys
-
-Commands with properties:
-- sendInput has "input"
-- closeOtherTabs has "index"
-- closeTabsAfter has "index"
-- renameTab has "title"*
-- setTabColor has "color"*
-- newWindow has "commandline", "startingDirectory", "tabTitle", "index", "profile"
-- splitPane has "split", "commandline", "startingDirectory", "tabTitle", "index", "profile", "splitMode", "size"
-- copy has "singleLine", "copyFormatting"
-- scrollUp has "rowsToScroll"
-- scrollDown has "rowsToScroll"
-- setColorScheme has "colorScheme"
-
-Majority of these commands listed above are intended for the command palette, so they wouldn't make much sense with keys assigned to them anyway.
-
-### Future Considerations
-
-One day we'll have actions that can be invoked by items in the dropdown menu. This setting will have to live somewhere. Also, once we get a status bar, people may want to invoke actions from there.
-
-## Solution Design
-
-### Proposal 1: Keyboard and Command Palette pages
-
-Implement a Keyboard page in place of the Actions page. Also plan for a Command Palette page in the future if it's something that's heavily requested. The Command Palette page would cover the missing use cases listed below.
-
-When users want to add a new key binding, the dropdown will list every action, regardless if it already has keys assigned. This page should show every key binding assigned to an action, even if there are multiple bindings to the same action.
-
-Users will be able to view every possible action from the command palette if they'd like.
-
-Use cases covered:
-- Add key bindings to an action that does not already have keys assigned
-- Edit key bindings for an action
-- Remove key bindings from an action
-- Add multiple key bindings for the same action
-- See all actions that have keys assigned
-
-Use cases missing:
-- Create an iterable action
-- Create a nested action
-- Choose which actions appear inside the command palette
-- See all possible actions, regardless of keys
-
-* **Pros**:
-- This allows people to edit their actions in most of their scenarios.
-- This gives us some wiggle room to cover majority of the use cases we need and seeing if people want the other use cases that are missing.
-
-* **Cons**:
-- Unfortunately we couldn't cover every single use case with this design.
-- You can't edit the properties that are on some commands, however the default commands from the command palette include options with properties anyway. For example "decrease font size" has the `delta` property already included.
-
-### Proposal 2: Have everything on one Actions page
-
-Implement an Actions page that allows you to create actions designed for the command palette as well as actions with keys.
-
-Use cases covered:
-- Add key bindings to an action that does not already have keys assigned
-- Edit key bindings for an action
-- Remove key bindings from an action
-- Add multiple key bindings for the same action
-- See all actions that have keys assigned
-- Create an iterable action
-- Create a nested action
-- Choose which actions appear inside the command palette
-- See all possible actions, regardless of keys
-
-I could not come up with a UX design that wasn't too complicated or confusing for this scenario.
-
-**Pros**:
-- There is full parity with the JSON file.
-
-**Cons**:
-- Could not come up with a simplistic design to represent all of the use cases (which makes the settings UI not as enticing since it promotes ease of use).
-
-## Conclusion
-
-We considered Proposal 2, however the design became cluttered very quickly and we agreed to create two pages and start off with Proposal 1.
-
-## UI/UX Design
-
-![Click edit on key binding](./edit-click.png)
-
-The Add new button is using the secondary color, to align with the button on the Color schemes page.
-
-![Edit key binding](./edit-keys.png)
-
-![Click add new](./add-click.png)
-
-![Add key binding](./add-keys.png)
-
-## Potential Issues
-
-This design is not 1:1 with the JSON file, so actions that don't have keys will not appear on this page. Additionally, you can't add a new action without keys with this current design.
-
-You also cannot specify properties on commands (like the `newTab` command) and these will have to be added through the JSON file. Considering there are only a few of these and we're planning to iterate on this and add a Command Palette page, we were okay with this decision.
