Feature request: some way to group/categorise mods

### I am planning on implementing this myself

No

### Describe your request

The mod list can get really confusing with all the helpers and disabled maps cluttering it, so some support for sorting mods into categories would be great. Currently the way to do this is prefix every mod you install so they're sorted by prefix in alphabet order, and while this works, it's easy to lose freshly installed unprefixed mods, as it doesn't separate the mods in any way (also no bulk enable/disable).
The easiest way I (not a modder) see to implement this is to create a .txt file that lists category names and mods within them, and change the UI to be able to list and expand/collapse categories, list and enable/disable mods within categories, and enable/disable the entire category (oh, a .txt file for category blacklist). Similar UI is already implemented as options of mods (Speedrun Tool and Hyperline use this, for example). UI to create/edit/delete categories isn't required, but would be appreciated. Maybe categories could have their own folders so the mods folder is easier to read.
