Been looking through this UI, as I set it up. But I stumbled into something not supported by it, but it still changes it.

The Currency tab goes missing.

JP/HP/VP/Coins and so on, unable to find a quick key for it, nor the actual tab under the character panel.

Edit: Added Picture.

Unless you have it hidden somewhere else, I am unable to find the location.

Edit 2: Added Temp-solution with addon, Currency. http://www.curse.com/addons/wow/currency

Fixed by 6abee0f, I think I'll release a small update this weekend.

TY, will fix it, it's quite a strange bug, I wonder what causes it....
I've never run into it, cuz I always used a hotkey to open that tab.
