Catagories in knowledge window

[sparkicks]

Is it possible to seperate all your spells into personal catagories? i knwo this might take a lot of work but for each seperate class maybe to have custom knkowledge window where subcatories with large icons represent lines of spells
for example selecting a group taunt for a guardian would listen down a timeline of all the group taunts from 1-80 or the ability to view all current spells only...

any way that can seperate spells into easily managable lists where missing one out or getting the right spell without knowing the name can be easily viewed
