wmbday is a small dockapp that reminds you of birthdays. It can take an arbitrary number of birthdays, and will display the next four upcoming birthdays. By left-clicking a name, you can see the remaining days until the birthday. The colours of the background and the font can be customised.
The wmctrl program is a command line tool to interact with an EWMH/NetWM-compatible X Window Manager. It provides command line access to almost all the features defined in the EWMH specification. It's possible to, for example, obtain information about the window manager, get a detailed list of desktops and managed windows, switch and resize desktops, change the number of desktops, make windows full-screen, always-above, or sticky, and activate, close, move, resize, maximize, and minimize them. The command line access makes it easy to automate these tasks and execute them from any application that is able to run a command in response to some event.
wmdropzone is a simple Download Manager for your WindowMaker Dock. You can enter URLs manually or paste the current X-Selection. You can DragNDrop the Locations from (for instance) Netscape onto the Dockapp, too. It uses GNU wget for the retrieval. Throttling down downloads is supported through a supplied patch to GNU wget.
