The notifications come back in just about the same way the Algorithm scrambles timelines on the social media apps--its just like they're trying to keep you engaged in using the phone.

Ideally, the notifications should have two very simple views: a linear list by time, a grouped-by-application list and the ability to mark and sweep them away.

Or maybe at the most, an archive all notifications sweep that you can re-open if you remember that you wanted to see an old notification.
