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
