To communicate, simply type something in the note that the other person can see in real time without having to press send. They will also be notified of changes to the comment.
For each person in the note, a corresponding color will appear (just for a moment) so that everyone knows who wrote what. You can also swipe right from the middle of the note to see the name of the person who wrote the message, as well as the time stamp for when the message was written and the corresponding colors.
Now you can communicate secretly with your friends or family.

You can do this with any text in your notes, as well as photos, videos, links, drawings, or any other attachment you add to your note.
