There are a bunch of posts on the internet about using git worktree command. As far as I can tell, most of them are primarily about using worktrees as a replacement of, or a supplement to git branches. Instead of switching branches, you just change directories. This is also how I originally had useed worktrees, but that didn't stick, and I abandoned them. But recently worktrees grew on me, though my new use-case is unlike branching.
