I previously kept Grab.app on Mojave 10.14 by simply copying it over from High Sierra 10.13. I prefer the simplicity of Grab over the new Screenshot.app, and I hate that Screenshot adds a drop shadow.
Alas... Grab from High Sierra 10.13 is dead on Catalina 10.15, as Apple did not maintain backward compatibility in AppKit. RIP.
