With the new sorting capabilities, how possible is the following type of UI mod for the knowledge book (really, only concerned about spells/abilities myself)?
The idea is to sort by category, display specific information about the spells, within a category. So, the sort order would be:
Category>Spells>Level
If you can't do a multi-level/complex sort, just sort by Level or Category showing the appropriate metadata about the spells.
Something like this (I'm not a UI designer and this shows, but just trying to get the idea across):
