This is the best looking and functioning ROM I think I have used. I had UD 3.5.0 for awhile and thought that topped anything I'd used. I have used most of them.
This feels and acts like nothing else and it flat seems to work. The Ultimate Droid section in the settings is pretty neat.
So, I hope he slows down a bit and lets the themes catch up. I had, and really liked Red Glass on 3.5.0 and would like it on 5.0.
BTW, the link is for 5.0.1, it says 5.0.0, but downloads 5.0.1.
If you have issues, wipe data and cache even if coming from another UD ROM.
