Currently, when receiving notifications in the inbox, you get a number in the top bar on the inbox button. But when you open the inbox that number is gone and everything is marked as read. I don't like this behaviour.

I would like that only the messages that were clicked are marked as read and the number simply decrements. This would make it easier to follow-up on them. Also include buttons for marking individual messages as read, marking them as unread too, and a general button to "mark all as read". This would place a single click between my suggested behaviour and the current behaviour for those who still like the current (which I guess are probaby fewer than those who would prefer my suggestion).

My suggestion would be pretty much equal to how the Facebook notification system currently works, I like the UI and the functionality.

Question history about this here

Can we get an option to stop the global inbox from marking everything as read? was already asked here but this was declined simply because it asked for a setting and SO doesn't do preferences. I'm asking to modify the default behaviour.

Then there's Viewing inbox should unmark read items rather than all items but the so-called duplicate is not a duplicate at all. Also this was before the entire top bar was re-done and it was still the Stack Exchange MUltiCollider SuperDropdown thing.
