 When ##Nostr sync ? 😅 

 Nostr is not great for file storage. But take a look at https://github.com/hzrd149/blossom

 No note taking app beats TiddlyWiki. Single file concept, highly flexible. I use it since 20 years and can still read all old notes because it is simple HTML and JS. If you don't know it, it's worth a look.
