I like it. I have Skinner, but all I use it for is to remove border/texture and create a viewport and BF. I haven't had time to actually try my hand at graphics, yours looks great.
I really like your oUF layout as well. I've been stealin' your code from a lot of it, great structure for a noob like me to decipher.
Nice. Any addon or is it standalone outside the interface folder?
Does it break on Full-screen <-> Windowed?
it's inside the Interface folder, but outside the Addon folder. (with exception off remodded addons like Betterquest, doublewide, doublewidetradeskill)
should work with all resolutions, and window size.
That looks like an idea that I have banging around this cavernous warehouse that I call my skull. I have acutally started by building new textures for the Unit Frames (which are for the most part complete). However I still have a lot of work to go before I can show anything else off. Sleek textures ala Skinner are the the idea in the same vein as the OP's. I look forward to the OP's project with interest.
