I'm all for "Option" of 3 action bars on your screen, its very cumbersome in its current state (playing keyboard/mouse setup). Would be easy to have it listed under configuration so you can switchout whatever you like, im capped on macro's (that are in my reach on the keys) and have started to overlap macro's that dont conflict each other due to your current class.

Would Really REALLY like to see the option of being able to "Mark" an add like you could in lev quests, while your in a say dungeon or any party for that matter, however setup differently as that system just required more and more macros to use efficiently. WoW had great "Marking" abilities and could hotkey the "Signs" to any Key...Hotkeys.. More Hotkey Options preeeaassee!! and Thank you =)
