The ability to write alternative CLIs on top of Git is often touted as a feature (as well as a defense against criticism of the existing CLI). I'm not terribly excited by save/sync either. But as long as it doesn't have adverse effects, e.g.:

* promotes bad history patterns

* makes it easier to miss when unwanted changes are included

* makes it easy to accidentally push

...I see it as a good thing to have new UI patterns tried out. If nothing else, it can act as a counterpoint to show that the complexity of the Git CLI actually is necessary for some of the flexibility.

EDIT: I see now that "bit save" encourages using single-line commit messages, which to me promotes bad history patterns. That's too bad.
