One thing I think would help this is a dual repo setup with the local dev-only repo automatically committing on save (or if your watch is expensive committing unsaved editor state on pause). The repo could be short lived if you prefer (eg new per baseline repo branch or editing session) or a long lived series of stashes. But its history would be built into the editing experience and separate from the normal version control flow. I don’t think it would necessarily work for everyone but it could certainly fit how I work in exploratory mode without breaking my editing flow.
