It would be a good to get more insight into what has happened to photos that has been uploaded. How many are missing dates or location? How many new people/face was detected? Is there any photos that are corrupt or other errors? How many duplicate was detected. And also from this kind of report it would be great if it was easy to search for those photos in the photos view to inspect them. Increased transparency over Piculars "behind the scenes" work.
This would also have to include somewhere to watch these reports, like a kind of message inbox.
