Riffing with Brett about how richer interaction could be used for navigation, I thought it’d be nice to have browser back button functionality that’s as fast as scrolling. Imagine you have a little slider in (for example) the upper left of the window, and sliding the handle horizontally scrolled by the pages in your history. There’d be indents so it wouldn’t stop in-between pages, but you’d see the pages scroll by for the sake of visual confirmation.

Technically it would mean keeping more pages in active memory and not just cached on the hard drive, but hey, RAM is cheap these days… what’s a few more megs?
