WMII 2

WMII is a dynamic window manager for X11 and the next generation of wmi. Highly customizable and usable with keyboard and mouse, it boasts conventional, tabbed, and tiled window management with low memory usage and a vi-alike user interaction. Due to a complete rewrite, WMII 2 is highly modularized and uses a new configuration and inter-process communication interface that is oriented on the 9p protocol of the plan9 operating system.

General features include xinerama/multihead support, although this is not yet implemented. The window management system offers tabbed, tiled, and conventional window management as well as a customizable snap-to-border feature. Input devices are also highly customizable, with full keyboard control and improved mouse control.

Configuration features include an IXP configuration interface, remote configuration, and session support (through configuration). The official utilities included in WMII are wmiiwm (core window manager), wmimenu (generic menu), wmibar (generic bar), wmir (wmi remote configuration/shell tool), wmikeys (the shortcut handler), wmifs (virtual master file system server), wmiplumb (plumbing tool), and wmiwarp (pointer warping tool). There are also several contributed tools such as Szs3rd, which shows system, mail, player and other information, wmizer (configuration tool), status-rssw (Gmail Inbox checker status text presentation & other wmii things), and plumbrb (Plumbing handler with regex support).

Rendering features of WMII include a cairo rendering backend, Xlib rendering backend, style support, and antialiased fonts (cairo rendering backend only). The software offers POSIX compliance, although several GNU libs are not compliant, ICCCM compliance, and partial NETWM compliance without KDE-/Gnome-only crap. So, if you are looking for a highly modularized and customizable window manager, WMII is definitely worth a try.
