You should add a ‘tap to add to Contacts’ link - I think a vCard would work?

I don’t want to send a postcard right now, but I’d definitely like to store the number for later use. It’s actually kind of hard to do that, though, on iOS at least. Tapping opens up Messages, where there isn’t an easy way to add to contacts without sending a message, and long-press doesn’t seem to contain ‘add to contacts’ option. I’m stuck copying the number, launching Contacts, and creating a new contact by hand.

[Edit: Uh, and this is cool! Sorry to be the first commenter with a slightly negative post! I love it.]
