What’s also great is that you don’t need to do a pull in the other folder. Before I discovered worktree, I had my repository checked out in two places, so was either pulling both constantly, or when I needed the alternate, it was often very far behind and I had to pull a lot.

The great thing about worktrees is that everything local is still available in the worktree and vice-versa, you can even stash push on the one side and pop on the other. You also don’t need to push or pull on either side first.

I have noticed that for submodules, although they share the .git folder, they don’t share references, so you can’t see local branches and stashes between the worktrees, but sub module pulls are still quicker since they share objects so those don’t need re-pulled on the other folder.
