Ignore is useful for users who don't particularly care about the source going into the system. This is especially useful in combination with norename enabled.
DATabaseTwo is a standalone version of what will be replacing "Import" and "Generate" and thus eliminating the need for a complex import and export process. Custom DATs can be cared by Dir2DAT features and merging so there is no use to have advanced DB features. The new database, dats..sqlite, is a much lighter version, only holding the DAT information, systems, and sources.
