I really like one of the features I squeezed in just before the RC, it's a small thing that I've wanted to do it for a long time: Something borrowed from Facebook, where I found it super convenient. When you have no unread notifications and new ones come while you\re online, if you hover over the popup cards, they are marked as read. So if you do the hover (as an "I saw this") for all incoming notifications, you never have to visit the notifications page or click the "Mark all as read" button mid-session - your unread notifications count will stay at zero, without clicking anywhere. #catodon
