Anytime screenshots come up in conversation I have to recommend Flameshot, it totally changed my workflow with including them. You can create, crop, and edit screenshots really quickly and it's a must-install for me at this point. Open source and cross platform. https://flameshot.org/
Flameshot is great, the only thing that would be better is if you could video record a screen region using the same UI instead of just taking screenshots.
Most screen recorders are incredibly cludgy. They either require extra cropping and editing after the fact or tank framerate into being unusable. I don't understand the technical problems and the whys though.
