Greetings.
I have done a little playing around to the Delta 4.0 (which is btw the best UI out there IMHO) and added the "Current/Max" mana and mana bar to the EQUI_TargetWindow.xml file.
I had to do some photoshop editing to the image and recreate it to make space for the mana bar and numbers.
It only works on 1280 x 1024 and i'm using some custom target ring and Tking icons.
Please let me know if there is something wrong with it.
Hopefully you'll like it.
