Private note-taking app that syncs across devices easily by using a relay to store the notes encrypted by my private key, bonus points if I can set the relay so that it's one that requires AUTH to retrieve the notes, and the notes can be published to my public relays as a long-form, should I decide to do so.
A link/bookmark sharing app that allows users to create, edit, and share bookmark lists. Basically listr.lol, but focused on lists of web URLs, rather than lists of npubs, Nostr notes, or relays.
