Okay... Here's a new UI setup - mostly just changes in UF's from the last one. Admittedly, it's an ENTIRELY different UF style.
Power bar is on top, and turns into the castbar. Name changes to "HP% | DeficitHP" when not at full HP.
There's a few problems - this was the first time I'd played my Shammy since 4.0 patch (and about 4 months before it), so the Totem/Shield/Weapon timers were shoved to the sides hurriedly.
ZOMGBuffs just converted to Ace3, and the config menu is wonky (as in nonexistent) so it's buttons are on the screen as well (top button near center-right, and the earthshield tracker above the minimap, as well as a minimap icon in the lower left of the minimap). Those 3 items will go away as soon as ZOMG finishes upgrading. :>
Also, this shot wasn't in combat because, well, my gear is horrifyingly bad. ;-) Greens and blues, mostly. I was too busy trying to keep the tank upright to remember to hit PrtScr. *grin*
