Multiple Monitors

Hey All - I have a second monitor to the left of my main monitor (on mac)

… and Window.(\x, Rect(-500,0,100,100)) will show up on that left monitor…

When the second monitor is not connected it displays on the main monitor and I get a warning…

Window.availableBounds seems to show me only the dimensions of the main monitor - anyone know a way in sc to find out what the total available display geometry is? I’d like to control the behavior based on what’s available

thx !
