Think you can do this for the friendly side too? I know there's a lot of raid frames but for PuG BGs, this would be great for healers. It's easier to see and determine if people need help, for DPS/tanks.
But BGT is so very nice for me (spriest) to target flag carriers to mind vision, when they have a bunch of ascii chars in their names.
ps. I see you used to work on Grid. Yours could be like Grid without the ridiculous configuration nightmare. BGT is so clean and simple, it would be great as a BG party/raid frame!
