I generally use a quick flick of the mouse to switch focus between windows on different monitors. I generally keep the same application on a particular monitor so know where it 'lives'. I usually use the Keyboard `Alt`+`Tab` to cycle between windows that are covered by others, so from that POV it's quite confusing when `Alt`+`Tab` causes windows on the *other* monitor to the one I'm looking at get cycled.

Is there any way to limit the list of `Alt`+`Tab` windows only to the current monitor that has focus?

I'm on GNOME, not Compiz, on Ubuntu 19.04
