Create a MacOS like screenshot effect
One thing which I miss from my OSX (now called macOS) days is it's ability to create "pretty" screenshots out of the box. OSX screenshots have a nice drop-shadow effect and it centers the image with a faux border.
Not exactly same, but quite close is this
imagemagick command to achieve the same on Linux systems:
convert screenshot.png \( +clone -background black -shadow 50x50+30+30 \) +swap -background white -layers merge +repage result.png
Pretty happy with the result!
