kdelnk2wmaker is a converter which outputs data suitable for inclusion in Window Maker's menu from KDE links. The major difference from other such tools is that this one supports i18n and can output application names in your favourite language (if that information is included in the kdelnk file).
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.
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.
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.
wmmclient is a small Window Maker dock applet that connects to a specified MasqDialer server and prints out status information of the current dialup connection, if there is one. Its appearance is similar to the wmppp applet. Two buttons allow you to connect/disconnect to/from the specified mserver. LEDs tell you if you are connected to the mserver and if there's an active dialup connection. If supported by the mserver, the applet will print out some load information.
