Maelsturm, Asked me if I would post a few updates to this UI... Things pointed out were :
Group window
Target window
Exp bar %
Since Aalwein has not enabled any addon's or patches for his UI then I have to post the zip here..
Note, Target window 99% sure that should be fine now, Group and the Exp % may need lineing up a bit more....
All untested thats a job for you guys
