Sorting within the hotbar is a giant pain in the arse. I want to keep it organized by spells, actions, potions, items. This becomes particularly cumbersome when you learn a new spell and have to reorganize the whole damned thing, and even more so when you remove an item that gives you a power or skill (like the speak to the dead skill necklace) and some random potion gets put in there. I really wish you could set an auto sort by category and then rearrange within those categories as u like. Or something like that.
