I am currently using the Lodidodi UI and it's awsome. I have tried several different UI's and this is the best I have found. Unfortunatly it isn't to appealing to the eye.
I am looking for something as close to the functionality of Lodi's as possible but a little more visually appealing.
The problem is I get extremly picky about the smallest things. Like not having a close or minimize button on a window drives me nuts. Little things like that have turned me off of several very nice UI's.
I am seriously debating on writing my own but I know I'll spend a year making sure it's exactly how I want it and I was hoping their was already something out their that I missed before I put myself through that kind of headache.
