Thanks Linda. Yes, several (most?) clients have a web landing page for this. So if you “share” a note from that client, it copies a website link pointing to their landing page with that note displayed. So that somewhat achieves it. But that’s different than using a generic nostr uri in say, an email, or a PDF, and when the user taps/clicks the note link in the email or PDF, the app they’re using works with the OS to launch the preferred nostr client to view the note.
