Right now...we have quite a few controls to map, no? It would be fairly easy to make some sub-tabs, right?
What I'm talking about is the movement controls could go in their own tab, battle controls could go in another, (i.e. Shield Bash, Attack, Defend) and emote shortcuts would get another tag. This would greatly help when finding a certain mapping to change. When making custom controls, it's less daunting when they are split up in smaller sections. Of course, there would also be an All tab that would have all the controls the same way as it is now.
