WMII is the next generation of wmi. WMII 2 project is a dynamic window manager for X11, which is highly customizable and usable with keyboard and mouse. It supports conventional, tabbed and tiled window management with low memory usage and a vi-alike user interaction.

Due to a complete rewrite it is highly modularized and uses a new configuration and inter-process communication interface which is oriented on the 9p protocol of the plan9 operating system.
