Better Collections

The collections are a mess right now. Finding something here is a torment.

-Ability to sort collections at least by name (I don't know how they are sorted now, random?).

-Ability to interact with them like folders - custom subcategories, e.g. LORA/Style/Traditional art

-Selecting a Showcase for a profile as one of the collections

Also a small bug. If a collection is empty, it shows "This content is not available on this site" and blocks the collection list. And since the sorting is random, opening collections may redirect you to an empty one and automatically get you stuck. At least on .green
