There's something that bugs me ever since the introduction of folders in iOS and is still present in iOS 7.
Lets assume you have the app you wish to use in a folder (it happens with any app within a folder). You tap on the folder to obviously get inside the folder and then you tap the app to open it and do whatever you need to do.
Once you have finished using the app, the bugbear with me is that you now have to press the Home button to exit the app, and then you need to press the home button again to exit the folder and return back to the Home screen?!
Why can't it take a single press, from within the app (which is obviously inside the folder) to return back to the home screen (the app should close and it should zoom/fade all the way back out to the home screen instead of just closing and returning to the folder. No?
