WMpop is a Window Maker dock app that monitors a local (mbox format) or POP3/APOP mailbox to inform you when mail arrives. It displays the amount of mail in the mailbox (or unread mail if checked in the preference screen), a scrolling text with the email address of the senders (only for local mailbox at the moment) and a status led, indicating mail checking progression and errors. It can be configured and personalized (icons and sound) via a GTK+ GUI.
WMixer is a complete OSS mixer solution in dockapp form factor. All channels are supported, stereo channels balance can be adjusted, and main recording source can be set. Volume can also be adjusted using the mousewheel on newer mice, the mixer automatically updates if another program changes mixer channels, and it uses very little CPU time. There is also an "On-Screen-Display" feature to visualize current volume using a TV-like volume bar.
Sherman's aquarium is a screen saver, a GNOME panel applet, and a dock applet that provides an aquarium with fish and/or turtles. In applet mode, it can display lots of information, such as CPU load, temperatures, memory usage, and many other things. Both the applet and the screensaver are very configurable.
WMCPULoad is a program to monitor CPU usage. It is a dockapp that is supported by X window managers such as Window Maker, AfterStep, BlackBox, and Enlightenment. It dispalys the current usage, expressed as a percentile and a chart, and has an LCD look-alike user interface. The back light may be turned on/off by clicking the mouse button over the application. If the CPU usage hits a certain threshold, an alarm-mode will alert you by turning the back light on.
wmmenu is a "dock application" for Windowmaker that provides a button bar to launch applications from. The bar opens automatically when the mouse enters the button. Multiple instances of the program can run at the same time; each one provides a menu that it reads from a separate file, so you can have as many different menus as you want.
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.
