I've made 2 UI's i was happy with. I didn't finish either, but got pretty close. The chat box in the second picture is normally left of the "player" pitbull frame, but i have to move it when browsing the AH. When cataclysm hit i just couldn't bother anymore, it was too much work and have been addon-less since. I don't play any longer, but if i ever get back to wow, it wouldn't be to play (anything but the AH

), it'd be fun i think, creating UI's again.
In case you're wondering, non-cd spells aren't visible since they're keybound and i'm using a cooldown monitor, skills on cd shows up right above the action bar. On the second picture i have holy shock/short range judge (forgot name) to check range, and if i get locked out of my holy school.
