README OneStepBack

==OneStepBack==

OneStepBack is a Gtk 2 and 3 theme with some colors and embossed widgets inspired by the good old NextStep look. I'm old.

It is developed from scratch, is light and minimal, uses only three shades of grays and one color. That was the challenge.

It has been tested on Arch Linux with Gnome-Shell, Gtk+ from 3.16 to 3.22, a good amount of Gtk2 and Gtk3 applications. A lot of widget controls are still missing and it is not tested at all with unity or xfce.

==Version==

Current version is 0.991, released in July 2018.
