I built a similar tool a couple of years ago here: https://github.com/google/git-sync-changes

Both save uncommitted changes in a hidden ref.

Based on the README, the differences seem to be:

1. dura runs as a daemon while git-sync-changes is a one shot execution.

2. dura saves locally, while git-sync-changes syncs with a remote repo.

3. dura only does the save and the restore is manual, whereas git-sync-changes does both steps automatically.

I’m glad to see more people exploring this space. I think there’s a lot of untapped potential in tracking pending changes similarly to how we track committed changes.
