XNeat Windows Manager adds additional features to the Windows taskbar and system tray, that enables you to minimise any window to an icon in the system tray (instead of the taskbar), keep any window on top, set a custom transparency level, and also hide any window or tray icon.

The program allows you to re-arrange the order of the taskbar buttons by simply dragging them around. XNeat Windows Manager integrates into the right-click menu of the taskbar and system tray. It also allows you to change the taskbar appearance by hiding the Start button, system clock and other elements.

Note that this is the free Lite version. The Pro version includes additional functionality.
