When I click on the user icon in the upper right corner it opens a list of notifications. It shows all notifications, even after I read them.
Included in the notifications are messages that I have archived. This makes no sense.
I like notifications for new messages and changes to threads that I am following. However, not being able to clear the notifications means that I am always looking at the entire list to try and determine what is new. If I see a banner “1” on the user icon then I expect to click on the icon and see 1 notification.
