It's hard to virtually keep track of the people I'm meeting at WC4 or Launch and why I connected with them and details about them. I would like the ability to leave notes directly attached to a contact in the chat app. Notes that they can't see, just for me, to be able to keep track of notable things about them. This could be either attaching a note from the notes section to them, or just a little pop out note that exists only in their contact. I could see merits of both ways, but I think that linking a note to the notes section would be more robust.
