@andrewilley yeah, what i love about Poweramp is that what swipes do everywhere is so predictable.
I don't even look at my phone. Or I don't even have to struggle to reach the edge. Even in the middle of the screen, swipe does 'back' action.
I'm afraid of losing the pleasure of seamless surfing inside this app if horizontal scrollable lists come.
I think it makes a bit sense that swiping left and right do the sand thing, because, think of a new page as a new layer. You push one later aside to see the one under it.
Anyways, horizontal lists ruin this experience.
