WMScript is a system monitoring dock app for Window Maker. It allows you to specify a command and have the numeric result of that command displayed in the dock app's window. You may specify up to 5 things to monitor and the interval is configurable. This combines to make it a very flexible tool for system monitoring. It is based on WMiNet, and the look is the same.
wmalbum is a Window Maker dock applet that displays album covers for songs being played by XMMS. You must already have images of the album covers stored near the file being played. WMAlbum provides a handy circular menu for play/skip/etc, adjusts volume using the mouse wheel, and can replace wmxmms.
wmwork provides a monitor on a 64x64 mini window that helps you keeping track of your time. The idea is based on the Worklog program. In contrast to Worklog, wmwork is a graphical application designed to work with the Window Maker dock, but will also work with other window managers.
