One of my favorite additions in Lollipop is the native flashlight accessible by swiping down on the lock screen. If you leave the drawer open, you can toggle the flashlight off by tapping the icon. However, I have a habit of locking my screen right after I turn the flashlight on. When I wake my phone, there is no quick way to toggle the light back off without swiping down (requiring a second hand). It would be nice if they added an icon that would allow you to turn off the flashlight with one hand.
