Further digression: Gestures that require swiping are the worst, in my experience. Even worse than borderless buttons. They're undiscoverable and if there is any tutorial showing how to use them it's only shown once. I recently had to disable the opaque swipe-to-answer on my dad's Samsung because some jackass designed and/or business owner made that the default. I wish designers, etc, would all have to go through an annual boot camp where they have to watch older people navigate their products (without being able to intervene and help).
