Oh there was a Nip05 search thing.. didn't seem like it was hooked up tho.
Just thinkng.. For a tool that just focuses on relay configs, it'd be really cool to have it pioneer all the same configuration that gossip has. You could check out how the latest gossip client does relay configs, there are 4 or maybe 5 check boxes. Each has a description/tooltip of what they mean.
I think it's inbox, outbox, read, write, advertise. Though I'm not quite sure if gossip even publishes those flags or just uses them locally right now..
One other thing, what do you think about doing a nip for relay advertisements? I think it could be a nice nostr feature, that would make discovery of relays possible and was thinking future might try to draft one.
