I'm not. Got fed up with it and got rid of it last night. My new list of mods are all found here and my new UI is looking pretty fantastic. Will have to get some images up so you can see them.
Titan
TitanQuest
GypsyMod
Atlas
SellPrice
And that's about it. Titan is a very good, customisable bar which goes along the top (or the bottom if you prefer) and can show a whole host of things. Mine shows exp, location (inc co-ords), bags, money, quests (with TitanQuest), clock and some other stuff. GypsyMod basically gets rid of the whole bottom bar and replaces it with just buttons. Since I never click on the Char or Quest buttons etc, there's no need for them to be there. I just have a couple of rows of buttons which can be moved about. Plus it changes the char and target window in the top left corner to add more info and make it just look better IMO.
All in all, I think my UI now looks so much better and does exactly what I want without a whole load of other crap I didn't use. And do you know what, I really think I can notice the difference in lag and FPS!
As I said, will post some screenies later to show you. So, what are you using?
