wmsupermon is a universal monitoring dockapp. It can be used to monitor CPU usage, disk I/O, memory usage, swap, filesystems, space utilization, network traffic, wireless link quality, CPU frequency, CPU temperature, fan speed, voltages (without requiring lm_sensors), battery status (with actual, not "reported", discharge rate), traffic from your router, or anything else. It can open and maintain many dockapp windows with one dockapp process.
wmsystemtray is a system tray using the freedesktop.org system tray protocol that was implemented as a Window Maker dock app. It has the ability to display more than one dock window to make room for more tray icons, and the ability to scroll through the icons if more are present than will fit.
wmsystray provides a system tray compatible with freedesktop.org's System Tray Protocol specification. Basically, it serves as a system tray that allows other programs to show icons in it. For example, if you enable GAIM's System Tray Icon plugin, wmsystray will display GAIM's systray icon. Its intended use is as a Window Maker dock app, though it will run in other window managers as well.
wmudmount is a Window Maker dockapp that can be used to mount filesystems. It uses udisks to handle notification of new filesystems and mounting of the filesystems as a non-root user. It also includes a mode to display the mounted filesystems with the least free space percentage (similar to wmfsm).
wmweather displays your current local weather conditions. After supplying a 4-character METAR station identifier code (most major airports have one), it shows station ID, time of the last update, temperature, dew point, pressure, humidity, and wind speed. The various entries can be forced to display in a variety of different units.
