Love your UI thread, mate- rate up!
I haven't used eePanels or Bagnon before, but I have used similar mods to the others you mention.
Instead of Pitbull, I use
X-Perl UnitFrames. I stopped using SimpleMiniMap since Bongos provides pretty much the same function- letting me centre my map on the screen. I use
Koordinatorfor coordinates, as it's more configurable (and I have trouble seeing the smm coords), although I know Bongos doesn't let you scale it down. Instead of Elkano's BuffBars, I use
Morganti's buffbars as they're more compact, and I like their look. I'll have to put up a SS later.
Another mod I use now, which you may not like because of the space it takes up, is
MobInfo2. It keeps a database of the mobs you fight, and shows the information when you mouseover them.
