Testing it out as a user, the slide transitions didn't feel as responsive to swipe velocity as I expected. In particular, if I swipe even a small distance but quickly, I expect to trigger the transition. I just tested it with iOS and Android, and they both seem to do it at least for left-to-right transitions of home screen pages, and Android does it for the top menu.
From looking at [the source](https://github.com/kenwheeler/slick/blob/master/slick/slick....), it doesn't seem check for velocity; it just applies a distance threshold. Have you considered having the threshold respond to swipe speed so that faster swipes over shorter distances trigger transitions?
