Hi Mathias.
I have recently started using "Minimize to tray instead of closing".
It would be really useful to have a configuration setting to "Start MC minimized to tray" so I can start it automatically with the OS and have it in the tray ready to use.
Also, once minimized, the only ways to actually close MC are:
Right-click the tray icon and click "Close Multi Commander (I do not really want to reach for the mouse) or
Choose the File menu and select "Exit"; but... then I have the "Are you sure you want to exit Multi Commander" dialog.
It would useful if that dialog could be suppressed with a configuration setting, so that MC closes immediately.
