Tray Pilot allows you to hide the System Tray icons. It might be useful if you have too many icons in your System Tray and there is not much place left for the buttons of your running applications on the taskbar. Just click a small button to the right of the System Tray, - your System Tray will hide and space for the taskbar buttons will be expanded.
