I dont know if you understand what i want to accomplish.
Here´s a little better explanation:
Lets say i open an app for example iboooks.
I read a couple of minutes before i have to go away.
Now I want the iPad to automatically press the home button for me after ex. 1min.
When i come back to the iPad i can see the springboard.
I hope you understand.
