one of my most go to things is I take a lot of notes from screenshots.
My workflow is take a portion screenshot on macos and put it into Notes App, or Microsoft Word or Email.
Command Shift 4, drag across screen to select area, and immediately you can see an preview that screenshot has been taken. This icon stays for 5 seconds and saves by default to desktop. You can drag this preview to any of the above app to put it in directly.
I wish windows had this. Windows has portional screenshot right now, (Windows + Shift + S) but this drag thing, would have been super convenient. Call it a minor nitpick but these small UX improvements are the only things that can be improved in modern OS.
