I would like to see a Nostr app focused almost exclusively on contact management. A Rolodex for “permissionless phone numbers”.
Maybe bring in a few additional functions that make sense ( like event signing npub1claveqd4fwqj5rsssmg3f5sa97qc8sh8rq5x607em9s8hth3t54qyc539g (npub1cla…539g) or secret sharing a lá Horcrux mplorentz (npub16zs…92l7) )
So you have an app whose surface area is just managing your own account and the relationships that you have to other accounts. A little black book.
