Not sure if you are looking for specific features or request or a UI as a whole but I've been using a UI that has been the same for EQ and simular for EQ 2. The UI I used in EQ was Dirty Delta and in EQ 2
Delta Purple. I have a few screenshots of EQ but don't have a place to put them.
Was hoping that whoever created the delta series or someone that used it was going to be doing something for Vanguard.
I used a bit of a different one for WoW called Insomniax but that was mostly modular pieces.
