TrayIt! can be downloaded now from Winaero. TrayIt! is an old abandoned app that still works for this purpose. It saves precious taskbar space when you don't want to interact with the running program constantly but need to control it once in a while. But it is just the convenience of having a constantly running program work from the tray and not interfere with the Taskbar buttons that makes so many program developers use the tray. It was never designed to be the place for long running programs. The notification area as its name indicates is actually intended only for showing notifications.
