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.
WMTime is a Window Maker dock app that displays the time and date and gives you some nice additional features too. It provides a realtime morphing interface (analog <> digital mode), auto-scaled and anti-aliased hands, localization that displays the day and date in various languages, and three user-defined launch commands.
WMTimer is a dockable alarm clock for Windowmaker or Blackbox which can be run in alarm, countdown timer, or chronograph mode. In alarm or timer mode, you can either execute a command or sound the system bell when the time is reached. WMTimer is configurable through the command line or the GTK GUI.
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.
WMgMon is a generic monitor applet for WindowMaker and Afterstep. It can display CPU, I/O, memory, and swap usage, as WMMon does. It can also display the result of other programs, as WMScript does. The result can be displayed as a gauge, a histogram, a percentage, a number, or any combination of those. WMgMon's advantage is that it lets you configure what's displayed in its configuration file so that you can tailor it to your preferences and easily extend it by adding new monitoring functions and new scripts.
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.
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.
