Good idea but I cant align left. I have 2 monitors side by side (secondary on left, primary on right) The desktop spans both monitors. The left hand usually is set to HDMI #2 which displays my PS5. When I set MP to align left, it aligns to the left of monitor 1 (which means it is not visible until I switch back to HDMI #1). If there was an option to "Align left on primary", that would work.
However since I now know how to create a shortcut, sidebar isnt 100% critical. I can just throw a shortcut into the taskbar if you dont want to offer adjustable delay
