Improvement for notification hub

[SystemDebugger]

Hi,
I've used the notification hub feature for a while, and I notice when there are multiple notifications, I am only able to go to the next one by dismissing it.
I don't exactly want to do that, so I think it would be great to scroll through them instead of dismissing it (to dismiss, pull down on the expanded notification).
On that note, I would also like that a clear all button exists in case we want to clear all of the notifications.
Thank you,
