One irksome thing I've noticed with sampling nUI is that it uses Blizzard's default classbars (demonic fury, burning embers, chi, holy power etc) which are pretty ugly and not very helpful at all. Plus they're smack dab in the middle of my screen covering part of my char.
Two questions:
1. I could use classbars created with WeakAuras no problem I'm sure, but then how would I hide the defaults?
