Looking good!
Is that a NIP-17 button? :)
Discussion
That will be, but I’m not sure about how to choose between NIP-04 and NIP-17 for ‘starting’ conversations. Let’s say you send a NIP-17 DM to me on Amethyst and I always use a client that does not support that. I won’t see your msg. I know it’s not Amethyst’s problem but that’s a bad UX, especially for newbies.
Most clients don't support NIP-04 anymore.
You can send a public message in that case: https://github.com/nostr-protocol/nips/blob/master/A4.md
