I also am having the issue with lack of tooltips (although I have to admit, this would be less of an issue if they hadn't changed what a lot of the icons look like ...)
Another issue I am having is when I try to use the .ini file you include for set-up (the one that, in theory, gives me the same layout as the one pictured here.) Not only does it not seem to work for me (my windows are all over the place when I log in), but when I attempt to tab my chat window, it crashes the game back to my desktop. (That's not just this UI though, I've had the same problem with others as well; only exception to that was with eXtreme UI ... part of the installer creates that file and installs it with the UI. Can you do that for yours? puh-leeze?)
Other than that, I love this UI, and I can't wait to get it figured out so I can actually use it.

Keep up the awesome work.
Oh, and I apologize if this is less than coherent ... it's early, and I haven't had my coffee yet.
