Just recently started using #git's #worktree feature, and now I wish I did this years ago. Being able to not just view but do actual work in more than one branch in parallel — without having to stash/commit/checkout all the time.. absolutely amazing. I'm still new with this, so could be there are some things (good or bad) I have yet to discover... but at least currently this feels like the most underrated feature of git that I'm aware of.
