Can there be an option / button / switch / feature that allows a Zorro session to minimize to a tray icon?

Obvious uses include running a very long process that the user does not want to accidentally interrupt, such as downloading data for 100 stocks, long training and backtests, all the while developing a completely different Zorro script (whose window is open).

You mean a script command for minimizing? Have you tried to minimize with the window handle (https://zorro-project.com/manual/en/hwnd.htm)?

I didn’t think of that. I’ll try it out. Thanks!

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:

I've been using CMDOW reliably for the past number of years.

I just put that in a scheduled task that performs various intraday file/server management activities.

This DOS batch file command minimizes all Zorro windows

for /f "tokens=1" %%a in ('cmdow /t /f^|find /i "Zorro"') do cmdow %%a /min
