Well I used to have aguf a long time ago, and then I switched over to Pitbull.
So I downloaded it last week again I think, to see how it had been updated and stuff, and I found it to be not customizable enough. The only alternative I'm willing to take to Pitbull is oUF, which does the same but is lighter ... but does require you to code the settings yourself (there's no in-game options).
I may convert my Pitbull profiles to it someday, I don't think it can be that hard to figure out.
EDIT: Oh yeah, I installed TipTac isntead of Cowtip now, and I'm liking it.
So far it's actually even better than Cowtip for my needs.
