[Feature request] Hidden group

[git-f0x]

This is intended mainly to clean up the other groups by non-destructively hiding unwanted desktop entries.
E.g. ImageMagick is a dependency for many things, but someone might not want it cluttering up the other groups if it's not used directly (Steam also creates desktop entries for Proton and Runtimes, which is a bit annoying).
The hidden group would be revealed by Ctrl + H, and is not visible otherwise.

Right now, unwanted entries can be placed in their own group, but this takes up space and is always visible ('out of sight, out of mind' would be preferred).

A potential different solution might be to have an option (maybe in the context menu; and maybe only on the Home page) to remove an entry from the App Library, but have some kind of menu somewhere, where they can be individually added back.
