Single Exp bar in a different window?

[betabry]

I've moved my experience bars into my player window but I would prefer to have just one that I can switch between adv/art xp. Tried overlapping them and also messing with the visible properties but I'm not sure how to get the right click menu option to switch between the two like you get in the Exp window. If anyone could point me in the right direction I'd appreciate it.
