FVWM-Crystal aims to create an easy to use, pretty, but also powerful desktop environment for Linux or other Unix-like operating systems. It uses the following programs: FVWM as a window manager and "main core"; different ways to provide icons on the desktop including support for many file managers and custom commands; xterm, aterm, mrxvt, or urxvt as terminal emulators; MPD or XMMS2 as music players (there's built-in support for controlling these programs), and several other tools for different functions, like setting a wallpaper or taking screenshots.
Fluxspace seeks to add advanced desktop functionality to pure window managers, like Fluxbox. The approach is to leverage existing tools, like Rox Filer and Idesk, with a flexible and modular Python API. Existing modules support desktop icons, panels, dockapp startup and swapping, and wallpaper management. Current features allow each workspace to have its own unique panel, icons, wallpaper, and running applets. Creating new Python modules is easy.
Ice Sound Manager was designed to ease the management of sound events, sound themes, and the IceSound server in the IceWM window manager. It is also intended to be an improvement upon the noble but primitive icesndcfg. The main improvements over icesndcfg include a support for sound event "themes", more comprehensive help, easy management and configuration of the IceSound server, a cleaner GUI interface, automatic starting of the IceSound server, and a more conservative approach to disk space usage.
IcePref2 is an updated, overhauled, improved, and perfected version of the original IcePref (which was abandoned by the original author). This new version includes many new features and bugfixes, and is a sub-project of the IceWM Control Panel project. It is optimized for IceWM 1.2.2 and better.
