Is your suggested feature related to a problem? Please describe.

When I want to find new mods I see a lot of optimisation/improvement/library mods.

Describe the solution you'd like

I suggest you to add categories for mods:

• Content mod (mods that add blocks/items/mechanics/etc.)
• Non-content mods (optimization mods, libraries and enhancement mods which don't add actual content to game)
• Add-ons for other mods

Describe alternatives you've considered

No response

Additional context

There are already tags on the site, but I can't remove all non-content from my search
