Zen suite, a theme compatible with GTK+ 2.x and GTK+ 3.x that aims to be simple, consistent, and visually appealing, is now at version 0.12.1.
Zen suite 0.12.1 features a menubar, toolbar, and icons, is available for both GTK+ 2.x and GTK+ 3.x, is compatible with Xfce widgets and the Xfce notify theme, and it brings pre-configured color schemes (Zen, Zen-blua, Zen-griza, Zen-nigra, Zen-nokto, Zen-verda, and Zen-papero).
The dependencies are the usual ones: Murrine engine version 0.98 (at least) for GTK+ 2.x, and, of course, GTK+ 3.8 at least for the rest of the features.
