Bring App to foreground?

Yes, you can technically use Xcode for jailbreak development (but you don't have to). If you want your app to be installed outside the normal sandbox, and in Applications then you'd build with Xcode without code signing, fake code sign (or use self-signed certificate), and then copy/install the app to your device, using scp or something similar (maybe have a script for this).

Jailbroken options for bringing your app to the foreground.

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.
