There's a lot more to do, and this isn't ready for actual usage, but the basic functionality is mostly in place and has decent test coverage. It can successfully upgrade a library last used with classic syncing and pull down changes via the API. Uploading mostly works but is currently disabled for safety until it has better test coverage. Downloaded JSON is first saved to a cache table, which is then used to populate other tables and later for generating PATCH requests and automatically resolving conflicts (since it shows what was changed locally and what was changed remotely). Objects with unmet dependencies or unknown fields are skipped for now but don't block the rest of the sync. Some of the bigger remaining to-dos: - Tests for uploading - Re-do the preferences to get an API key - File sync integration - Full-text syncing integration - Manual conflict resolution (though this already includes much smarter conflict handling that automatically resolves many conflicts)
