Screen stays awake for long periods of time.
Swipe gestures can cause you to turn the page when you’re not expecting. Like if you point and something and slide your finger horizontally across the screen.
Thoughts and Recommendations

Set passcode on a per notebook basis.
Move selected elements to different layers, pages, or notebooks.
