Oomm. ur UI number 3. had all the coolest ideas i ever seen, the "hidden" cast bar was an awesome idea.
The dogtag you used for mana, brilliant. i disliked ur bongos config but that was easy to overcome.
caith, is pretty, but not brilliant as OOMM3 was..
And that hunter UI is way to "cluttered" and needs to be cleaned up.
But, if you need inspiration i will be more then happy helping finding ideas as i use most of my time in school looking at addons XD
Edit:
And i hope mandacar findes some awesome idea for the addon Macaroon that will inspire you!
