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 Clave (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.
