We have found it's hard to find the notifications/ message for a thread reply and have started to lose some messages, yikes! It would be great if there was a feature where you can "catch up" and it show all of your unread messages including in a thread where you can choose to leave unread, marked as read or reply. AND/ OR A 'threads' center where you can double check replies that are specifically in a thread so they don't get missed.
