I just want to be able to keybind the action and macro bars to something OTHER than 0-9. 0-9 is a good default to set your interface on while people figure out how the UI functions, but it's absolutely awful for regular use once you get acclimatized to the game.

Also, I'd like to be able to use Shift as a modifier for one of my macro bars; it's a lot easier to hit than CTRL or ALT.
