i think that users should be able to sync tinysub settings across other devices - my idea for this was an OpenSubsonic extension that allows clients to store and retrieve a small amount of user-specific data on the server, which i've proposed here (and you can read more info there): https://github.com/opensubsonic/open-subsonic-api/discussions/274
i find that to be the cleanest option since it'd just be integrated into the server itself, and wouldn't require some third-party service
