Allow to export settings as text files suited for Git.
Like for Sync, allow to select all or custom information (settings, bookmarks, open tabs…).
For extensions, it would export at least the name, version, active status, store ID & URL. Also their settings/options would be great (if not in the same file, at least in a companion file, one per extension).
Reason:
Keep history of changes in a Git repo. And see a diff of changes.
Story:
I regularly backup my settings, config files, etc into a Git repository so that I can have the history of changes.
Having JSON files with pretty formatting would allow to do that.
