Great addon! Looking at screenshot and ingame videos I've always thought that the various hud's looks to be more of an annoyance then helpful. I like to have as clear view of the game as possible, but I thought I should give it a go. And now I'm hooked. :) Only thing I'd like to see different is the possibility to move the target of target and target of target of target (phew) separately and also to be able to scale them separately. Id like to have those at the top while my target remains at the bottom. As of now I have them turned off and Im using AG_UnitFrames to get that look and usability I like from my UI.
Keep up the great work. Its addon makers like you that makes WoW even more fun to play then what it already is. :)
