I found one but its really old and causes a ton of ui errors. Can anyone fix this or do one of you guys have a working one. This is the one I have http://pastebin.com/PWqzvGJW
no one has any ideas?
Shadowed Unit Frames has Boss Frames support that is very robust
I would highly advice against using WA for these purposes, Shadowed UF does exactly what you want and better (once you get through the options you can disable everything but the boss frames)
