It would be nice to have a “Mark all as read” in the alerts page (with an additional confirmation, to not mark all by mistake).
Currently you can only mark by selection, meaning max 50 at once.
After some intensive testing periods there can be literal hundreds of notifications (especially on a busy tenant) which could lead to paying less attention to it than it requires (or in other words - user fatigue can be an issue). Even more so for someone who was absent during that period.
I can say from other experiences with notification services that after a certain threshold I just stop paying attention to them. Here it’s a little different (as it’s part of the job ), but still it’s tiresome.
Bonus points if you give an ability to mark older than X
