-->

Slow the output of text to each line, replicating the slow modems of old, teletypes and sci-fi movie computer text.

Cathode, a now dead/obsolete fancy terminal for MacOS (similar to CoolRetroTerm) had a similar feature.

Proposed technical implementation details (optional)

Artificially reduce the speed new characters are output to a line in any given terminal session.

The effect as the graphics load in this video, but with all text, at an adjustable rate that can be set in the user config. -->

While this does seem like a fun gimmick, couldn't this be accomplished with some sort of shim executable like slow-output-down.exe that just starts some other commandline and buffers the output itself? I'm not totally sure that this is something that needs to be built in to the Terminal...

Yeah, I have a little python script I use for viewing old VT animations. That said, I did also think it might be neat to have it built into the terminal as a hidden feature which could possibly be triggered with a DECSCS sequence. I don't feel that strongly about it, though, because it's honestly not the sort of thing I'd use very often.

I agree this is 95% for show, but I really did find it made working with big lists in the command line much easier. Thought I'd float it just in case.

I've found some python scripts that replicate the effect and while not remotely sane to pipe every terminal command to it just for eye candy, since what I'm mostly dealing with is from my own scripts I can just tack on some code to them instead.
