Currently the notifications view shows notifications for every issue/PR that you are subscribed to, with no visual feedback about mentions to you. There is a "Participating" tab, but that's a click away and easy to miss.
It would be really nice to have a visual indicator of the importance of the notification. In my mind they would have this order of importance:
Not really sure if all this is doable with github's API, though.
Just to give an example, it would convey the information as I show here (but probably with a nicer design):

It's possible but I don't think it's useful to show such info for all notifications.
Those 4 level I mention are just an idea. What I think is useful is to have some sort of visual indication of how important the notification is.
And if that's configurable it would be even better (for instance the ability to configure a color for each type of notification reason).
There is an online tool available that filters the notifications in different reasons:
I wish GitHub auto-sorted notifications based on importance. "Importance" being calculated based on what I usually prioritize and other hints, using machine learning. One can dream though.

You mean like Facebook prioritizes your feed? I don't think developers would welcome that much.
The available information is incomplete and not particularly useful. Each notification could hide multiple comments and actions, but GitHub will only choose one of them. We can鈥檛 trust that it will choose the one you鈥檙e looking for so we shouldn鈥檛 show this info.
