We initially didn't plan to enable adding new contacts in eNuts in the way a nostr client does. I need to evaluate whether this functionality is relevant within the context of nostr integration. The original concept allowed users to input any npub and view the contact list without providing options to modify their nostr account by adding or following users.

Regarding the NIP-05 link, it is quite informative. If we include the NIP-05 URL, we might need to reassess the necessity of the checkmark; simply including the URL might suffice.
