Well, I had no idea that it was even remotely questionable in Blizzard's eyes, so I'd be one of those guys that got banned for "ignorance of the law," so to speak.

I did get an add-on last night that does exactly that, except without changing my ui more than just adding buttons. From Curse, I found "G15 Buttons (continued)." It just adds 54 (actually 50 since you can only have 120 something buttons and WoW uses the first 70) buttons that are movable and can be spaced out however you like. Thank you for your input : ) Definitely worth knowing that I might have been doing something wrong!
