Large Exp bar

[skipsandwichdx]

I like WoW's exp bar, which was a long bar that ran across the entire bottom of the screen and showed experience. I play with all my windows in a bar across the bottom of the screen, so it would fit well.

Is there any way someone could do this? Would only need the yellow bars, I think, since it's so big. Maybe a percent done label in the middle of it?
