They need to provide some kind of easy control for that screen turn off. I really don't like leaving it on when I go to bed with a download happening - even thought I have the auto power-off option selected. That's a couple of hours of screen burn-in I just don't need!

Home menu. Controller settings. You can turn off the screen from there in any application.
