Sizzy

Syncing the scroll position between devices can be useful, but given the fact that all the devices have a different height, you'll never end up in the same spot on all of them.

The Page Navigator plugin for Sizzy allows you to easily navigate a page by section or h1, h2, and h3 elements. When you click on the "next" and "previous" buttons, all the devices will navigate to the exact same spot.
