Totally get that.. I actually don't like alt-tabbing between windows, I find it clunky.. Much like you don't like to turn your head to look at other screens.

Much like you don't like to turn your head to look at other screens.. :-) Last detail to add is that I use Powertoys FancyZones in Windows 10 to set up zones in my screens that let me snap windows into specific layouts easily on the side monitors, so setting up dedicated layouts per-monitor is more intuitive and easy for me.
