I had that exact same problem with my iPod 5th gen after I updated to iOS 7, those All and missing didn't show up at all. However.... When I woke up this morning, both of them had things populated in them, so not 100% sure about that.
Just downloaded ios7. Have one question you guys know on the ol. IOS that you press tthe home button hard to delet the bbackground app and click the apps to delete. Now with this new version doesn't allow it. I just don't want to keep the stuff running and wasting all my data.
I must commend you on a well written, very comprehensive look at the new OS layout. By far the best I've seen on the new OS7.
While I am not an Apple camper, I forwarded your review to my Apple friends and they found your review very indepth and enlightening as they did not accept the new layout. They now have a better perspective on the new additions and advancements.
