My fingees can't keep typing --network, --source, etc. I want -n, -s, etc

You have env variables. Can't remember off the top of my head but it's listed in the help docs.

But I agree we could add some short flags.

This would definitely be nice to have for as many commands as possible. It's standard in many other popular CLIs.
