I feel that preventing an app from supporting multitasking doesn't violate Apple's guidelines. Apple should have felt it too. If you application doesn't actually need to run in background, you can very well prevent it by enabling "application does not run in back ground" key.
I bet, Apple won't sue you.
Not sure what your actual question is (I honestly don't understand it), but the box is specifically meant to disable any kind of background running of your application. If, for whatever reason, you do not wish your app to stay alive in the background, check that box.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
