With the arrival of AF 2016R2 notifications changed considerably. One of the features "lost" is reporting on notification delivery. You now simply get an annotation that x number of subscribers where notified.
I would like this to be improved to include a notification delivery report. I would suggest implementing this as a sub event frame that contains the list of subscribers, how they where notified (email, webservice, ...) and the status of the delivery.

The add-in to excel was also useful when customer is trying to create a report about when, who and how they received the notifications. Currently, with new version, we have to retrieve EF with Annotation and only looking at the Annotation column is insufficient.
With the introduction of the new Notifications, the prefer way to view the notifications history is via PI Vision. Have you considered doing that?

Some additional comments to the description. The old notifications had the advantage that, show me the notification history for last X days, then the table with scrollable bar was showing.
To get the similar table information out in AF, in the newer notification, it's very tedious. Steps involved are, Show event frame history -> Move hover every Anootation, double click on it, go to description and then look for the information there. Nice if, show history view that was available in old notification can be remade to newer notifications in AF
