Bah, you remember how quick I am on the forums Guice, sheesh!
Without .. okay, well, there is:
Vika's WatchDog,
here
Inokis's Clear Hud,
here
Kaitlin's MiniGroup,
here (the page tends to be *very* slow, however)
Nurf's bars, a (heavily) modified version of MiniGroup,
here (not sure if they work SA or not)
and, there are a few others out there ... Perl, something like that, check the other sites, Curse, UI.WorldofWar.net, WoWGuru ... there was a list of some of them on the Blizz forum, but it's down right now ...
