The latest build of Reflections has been submitted to the App Store. :)

Major changes include the ability to save photos to your camera roll, and from there you can use them as Wallpaper! Also, a new tag view has been added for all you Flickr users who actually use tags as your primary means of organizing photos. Finally, to round out the significant stuff, the tag cluster view will now let you add multiple tags from that cluster, without taking you back to the tag list after each one.

Look for it in your update queue soon!
