A minimistic Linux window manager with css style config
Our take on a basic window manager for Linux which adheres to the philosophy of "do one thing and do it well." As a result, this window manager only manages windows and does not provide any supervision at all. Instead it relies on another program, such as wbar or web.de, to actually provide that functionality. And in order to keep administration to a minimum, there is only one config file that can be manipulated to change the appearance of the window chrome using css styled syntax.
