I've started asking addon authors for permission to distribute their work as a collection. No promises yet…Thanks for posting this screenshot. i am spending from now till mop release cloning this ui for my mage..
My video card melted down (literally, black smoke and everything) the other day so I fell behind schedule. I installed a replacement late last night but need to buy a bunch of adapters to get my screens plugged in. Hopefully late tonight I can find a couple of hours to finish off the gcd/cs/holy power bar. I think I might steal Kait's idea for using cropped auras as bars. I had used them behind unit frames to highlight states like no seal/no righteous fury, need cleanse, etc. His bar idea is very clever and I think it's the kind of animation that improves a UI rather than being needless noise.
Writing my own threat meter has been more work than I thought. It's quite a boring bit of code to write…maybe I'll just use weak auras for that.
