wmsystemtray is a system tray using the freedesktop.org system tray protocol designed as a Window Maker dockapp. 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.
For comments, see the original dockapps.org entry.
This dockapp is not maintained by the Window Maker Developers Team. Please visit the dockapp's website for downloads.
