I remember setting some reasonable “raise timeout” and it worked well for me. For one use case, I had a workflow with two full-height overlapping windows (vim, xterm) and little mouse shifts toggled them up/focused.

Alt-tab didn’t work because its mru usually gets spoiled by other (browser) windows. If only there was a setting that fixed alt-tab mru into a stack. Alt-tab-tab to switch to app which started second may be much better than mru for some workflows, because you can always predict what it does with certainty of 1.
