To answer your question, not just minimize, but make the window disappear from view and from the desktop entirely, and leave only a Zorro icon in the "taskbar notification area", otherwise known as the "tray". Whether it means adding a script command or a new button to the Zorro interface, or simply changing the default behavior of the minimize button, it makes no difference to me.

Right now, the easiest workaround is to use an external app that minimizes windows to the tray, like Traymond. I'll try it out later:
