"Imp" is the short for Improved (also I've been playing too much Doom lately :P)
Today I've opened gnome-look and found this amazing metacity theme by miguelmmg.
The concept is fantastic (somewhat similar to some oxygen themes), but there where some things I didn't like, so I changed that.
- Button outlines are now have less shading (that makes it more bright on dark themes).
- The titlebar separator is more bright.
- The titlebar is centered.
