In the windows client, detect if the window is off screen

Hello.  I've been using Tasker for an eternity, and recently discovered Join.  I'm loving it.  I have one request, however.  I use the Windows client on a laptop which is sometimes connected to an external monitor, sometimes not.  When the laptop is not connected to the monitor, I cannot "find" the Join window.  There is not an option to move the window if I right click on the icon.  Can you enable moving the window on right click, or add a method to detect if the window is on a display which currently doesn't exist?

Thanks so much!
