Query: I Love my Kindle, BUT.......................

I Love my Kindle, BUT.......................if it slips out of its protective notebook, which frequently happens..........or when you return to the page you left off and you didnt bookmark it, and you have accidently hit the advance button...........I really like my kindle but if you could just fix the notebook, and have some way to lock the page you are on, beside bookmarking it would be a much better experience.
