[Suggestion] Longer/extensible action bars and saving bars by class

[Frein]

As for the first suggestion, I find no problem with how the three action bars are currently set up. There is little reason, imo, to change how many actions are displayed at one time. Don't we have enough clutter on the screen already?

No reason? There definitely are two gigantic reasons: To be able to tell how long you have left on your cooldowns and to be able to bind all your bars at once.
