[Anm]

I agree with munificent, with the precision of the scroll in the current implementation, but that seems trivially fixed with a snapping behavior.

There are keyboard short cuts and clickable side arrows to turn the page, though why they decided to override [space] with autoscroll, I cannot comprehend.

The scrolling feels backwards, now that I'm gotten used to Apple's tablet-style reversal on the touchpads. I'm sure this makes sense on a scroll wheel. Not sure if there is a way to detect the default scroll mechanism.

Overall, thumbs up for many long article applications.
