icedman / custom-window-controls

Theme the Gnome Window control buttons.

git clone http://github.com/icedman/custom-window-controls
make

Warning:

This is highly experimental. A set of buttons is drawn over the existing ones. For a purely css solution (Gtk3 & Gtk4 apps only though) see these files:
