Option for asking before leaving the app with back button

[csoltenborn]

Hi,

simple feature: quite often, I accidentally quit Music Player Pro by pressing the back button on the "home screen". Many apps ask if the really is what the user wants - can we have that, maybe configurable via settings?

Thanks

To be more precise: many apps require to press the back button two times to leave the app, and show a toast after the first press, which says that a second press is needed to leave the app. That's what I'd like
