I agree- when I was using that bar addon (whichever one it was), I turned the buttons down to 75%. I think they start default at 125%, but again, it's been a while since I had to re-tune my action bars so I could be wrong. Personally, I just hit the keybinds anyway (Ctrl-F1 through Ctrl-Fwhatever), so I don't need my aspects, or stance bars, looming over the screen.
