What does the blue book icon next to the notebook mean?

I just upgraded to v6.06 for Windows and some notebooks now have a blue icon showing a book with an arrow on it. What does this mean?

Hey @ConL,

That icon indicates a shared notebook. You can right click on the notebook title to modify sharing on that notebook. Hope that helps!

Thank you. That makes sense.
