Works with 64bit Quantum, so thats nice.
Text colours are not obnoxious but blend in nicely, wich is nice.
The animation is fairly simple, but it does not jump into your eyes going "I'M HERE, LOOK AT ME!!", wich is nice.
Tabs look normal, no edges or theme missing parts, even at high res, wich is nice.

So 4 out of 5 nice for me.
