Something I'm working on after seeing a Vertical party frame in the Dogtags 3 thread.
It's not completed yet - placement of the chat isn't perfect yet, I need to sort out some more buffs to show and debuffs aren't showing on target either. I need to make the focus frame vertical as well (basically, the opposite of the current Target frame). Cooldown placements and Omen need to be moved as well.
I've left it like this for now as I'm not entirely convinced this is the path I want to pursue, but it's different to say the least. Still not 100% certain about the rather heavy black feel at the bottom either.
Comments are more than welcome. I've included a screenie of my 'current' UI (as in, the one I use on all other characters - the shaman was a test case), for comparison. As I'm still not 100% sure on this one, your words of wisdom will likely have effect
