One thing that I think would be very helpful is some sort of tracker or number in your Inbox that shows how many total notifications you have. This is helpful since I often get behind on my Inbox and, since it loads “as you go” its difficult to tell easily how many total messages/notifications I have to check before my Inbox is “cleared”.
This could take the form of a total number of notifications, or a simple “tracker” bar that increased in size as more notifications piled up (and reduced as those notifications were cleared).
Thank you!
