It's pretty nice, especially in combination with slurp
which lets you select a part of the screen.
I have this mapped to my printscreen shortcut: grim -g "$(slurp)" - | wl-copy
, which lets you select a part of the screen to screenshot, and copies the image to the clipboard.
God damn it how have I never thought to do this before. Well guess I have something to do after work today lol
