What is your feature request?

Ability to make categories inside categories.

This would work lovely with #1112

What do you think this change is of?

• Visual
• Recipe Lookup
• Cheat Mode
• Plugin Integration / JEI Plugin Compatibility
• Others

Actually kinda the same GUI Class this would fall my Feature request would fall into #1158

I believe this would be too complicated for the end user, but doesn't offer much to the user as well, I think they should just all be separate categories.
