Sync data between devices

[SorrisoKDente]

It would be great to have a built-in sync function for Mangayomi, similar to what Syncyomi has for Tachiyomi through Google Drive. This would be incredibly helpful for users who access their library across multiple devices. It would automatically keep your library, history, and configuration data up-to-date, eliminating the need for manual backups every time you want to switch devices.
