I think the modded minecraft community would benefit greatly with a revamp of the category system.
Including tags to easily identify versions, whether a project is maintained or abanandoned, whether a project is Forge, Fabric, or some other modloader.
Also for modders, maybe tags indicitating no desire to port to Fabric or Forge respectively.
We updated the status to 'Planned', but it's more like 'Partially Planned'.
For starters things will be transferred mostly as is from Twitch, but we intend on reworking the project uploading section after we achieve stable and functional client and web versions.
The category/tagging re-do will include some of the elements you brought up here.
Versions will be searchable, but not as tags. You can see some of the search functions planned in out roadmap over here.
