What you need to do is throw away this new app, take the original Windows 8 app and improve it by making an API that allows third party developers that have apps on the system to link to the Photos app. It becomes opt-in for developers, users gain greater functionality and compatibility with services they use, and Microsoft has something to offer that competitors do not.
Complete agree with this comment.
And can we please have the people tagging and location tagging (and other tags/rating) features back that were there in Windows Photo Gallery - this would be awesome if you then linked it to the People App so that you could go from a specific Person to all of the photos you have (tagged with him) across devices and services of that person!
Also can we get back, or at have the hooks for other apps to provide, to do the other useful features in Windows Live Essentials Photo Gallery, such as Panorama, PhotoFuse and Collage.
In fact, blend the old Photo App with WIndows Photo Gallery with extensibility of providers and apps plug-ins and integration with People, and you would have an awesome Photo Hub experience which would really differentiate Windows 8.x from the other platforms.
