Zeta Desktop Environment (ZDE) is an X11 window manager and tools with enhanced usability and features for advanced users and developers. Some of its current sub-projects include imp, a library of core functions such as linked lists, zwl, a simple widget toolkit and light X11 wrapper, and zimwm, the window manager.
The Interface Window Manager uses Objective C and the GNUstep libraries to provide strictly minimal functionality, with all additional features in bundles called IWMComponents. It uses the GNUstep defaults database for user settings such as mouse button configuration, key bindings, and initial color settings, and is optimized for use in a strictly GNUstep environment.
WMab is a Window Maker dockable application that allows ACPI laptop users to graphically monitor the status of their power sources (i.e., whether or not AC or batteries are in use, and how long it will take to drain or charge the batteries). It also works with official kernels and with all Intel ACPI patches.
