This may be a long shot but...
I'm looking for a UI that can easily change between different classes. My current main is a Paladin, but I have two Shaman I want to level. I can't bring myself to level them, as everything is set up for the Paladin, and, honestly, the idea of trying to put everything where it belongs, again, gives me a headache. (My hard drive died, so I have no preferences saved from before it crapped out.)
I do have one big issue with most of the UI packs I've currently found: My screen is small. I have a 13" laptop screen to work with, with a max resolution of 1280x800, and I probably won't be able to get anything larger in the near future. I can't just scale everything down either, as it tends to get too small to read (my vision is not great, and I easily get headaches from eyestrain). So, my other issue everything has to be readable.
