I'm in a competitive place and my company pays me to keep my sword sharp. I do that with lots and lots of solid tooling... a ton of it being stuff I've developed myself over years =)

Myself, I wouldn't ever put this into an extension because I'm certain it already exists and if not, I can bang out the base functionality in a console within 5 minutes and throw a gist in my GitLab or do a URL-JS thingy. 5m is worth $20 to me! $20 is a case of beers yo!
