Iconic Tray - Minimize any window to a special new tray...
Iconic Tray is a tiny utility which lets you minimize any window either to the system tray (notification area in Windows XP), or to a special new tray provided by Iconic Tray itself (see image). This is very useful to hide seldom used or background applications which occupy your taskbar and hinder quick switching among those you use most often. Minimizing can be carried out with mouse clicks and/or system-wide redefinable hotkeys.
