Peksystray is a small system tray (also called notification tray) designed for all the light window managers supporting docking. As more and more applications use a small icon in the system tray to provide additonal fonctionalities and information, it becomes useful for everyone to have access to them. While "heavy" window managers (Gnome, KDE...) come with a systrem tray embedded in the rest of the desktop, lighter window managers (WindowMaker, fluxbox...) don't have this feature. Peksystray is a very simple and light implementation of a system tray for any window manager supporting docking, conforming to the System Tray Freedesktop standard.

Peksystray provides a window where icons will automatically add up depending on the requests from the applications. Both the size of the window and the size of the icons can be selected by the user. If the window is full, it can automatically display another window in order to display more icons.
