This would be great. I would also like to add that it would be great to add Comment from that page rather than being directed to the object and then having to come back to this page.
This idea would provide so much value to our organization. We waste so much time searching for updates within a project, it's ridiculous. We have to open up each thread to view all comments, then do a CTRL+F, so annoying. I'd like to be able to search by user, date, and keywords. If any of you remember, this functionality used to exist in AtTask and it got taken away.
We're seeing more need for this as well. More functionality around in app notifications in general. Our users are managing notifications via their email because they can flag them to follow up later.
It would be awesome to flag notifications, filter by type, date, change sort order, grouping. Search would be awesome too.
