DarkGraySmooth metacity window decoration
It's my first metacity theme, so please dont't hit me :) rather than that I like constructive criticism, so please feel free ...
This theme is based on the brilliant DarkX-2 theme by bvc (which seems not available out there anymore, so unfortunately no link here)
I use the "Sable Yellow" GTK theme and Sable is also a brilliant dark theme all over, but...
I just wanted an alternative to the window decorations, and more flat OSX like buttons with my favorite colors...
And, unfortunately, Sable has no window borders (or seems to be black ones) and it's some times hard to recognize a single window in a bunch of windows, so I added dark gray 2px borders, which solves the problem for me.
OTHER USED THEMES:
Icons => Mint-X-AbsenceOfBlue
Controls & Desktop: Sable Yellow 3.14
As usual, sudo copy DarkGraySmooth.tar.gz to /usr/share/themes (or maybe ~/.themes works also)
and select it in system settings.
