Sub-Categories for Better Organizations

Whenever you have larger servers for those that are moderators, admins, or even the server owner, your overlay can become quite flooded. What is the possibility of adding a sub-category? We already have categories, but what if we could divide it by one more? Allows for more organization for those running the server and allows users to view specific channels rather than constantly scrolling to search for a channel in larger servers.

Examples:
* category
+sub-category
-channel

(no sub-category)
* Food
   -ice cream
   -chocolates
   -fruits
   -veggies
==closed appearance(s)

(sub-categories)

          -chocolates
          -ice cream
   +Healthy
          -Fruits
          -Veggies
