Very interested as several apps I use regularly - screenshots (⌘-Shift-4), webex single-app sharing, screen flows, where this tool would be much much improved over SetResX + Display prefs.

$8 seems like a quite a bit, but is actually not that bad for the convenience. Love the preview, just not the bouncing zoom animation.

A few people have asked if they can switch off the continuous bouncing zoom animation. I might be able to add that option in an update.
