MultiLS cydia tweak moves the lock-screen notification list to a separate hidden page.
Whenever you receive a message, the right side of your screen will begin to glow, indicating you, that you have received a notification.
Slide from the right, to the left, to reveal the list. Hide it by pressing the home button, the sleep button or slide it back.
There is a timer, which hides the list in 15 seconds, to prevend useless battery drain.
