Side by side screenshots

Suggested by Jordan " A feature like http://snappy-app.com/ Specifically, they have a feature that allows you to snap a screenshot of a part of your screen, and it immediately keeps that screenshot as a separate item that stays above all other windows and you can see that little snippet on your desktop until you double click it to remove it. https://videos.pickleball.ist/conversations/00b78070-8a7a-534d-8d90-b0cf1914d37d I created a little video clip to illustrate how snappy app works… The specific feature that we love about it. Wondering if you have that feature already, or if it would be possible for you to add in the near future? "
