I have only tested this on 1 monitor, so I am not sure of the behavior across monitors.

@cmschuetz - I just saw your notes, thanks for the feedback!

I switched to using Sway since I've been migrating towards a Wayland-oriented setup. If I have some free time I'll take another pass addressing the feedback.
