So you have scrollable divs with momentum for iPad 4+ and you have consistent scrollable areas for all desktop and mobile platforms.

Sexy zoom feature, you can "zoom-in" the content of any nicescroll'ed div. Nice to use and nice to see, all the content of the div in fullscreen mode.

It works on desktop (double click on div) either in mobile/touch devices using pinch gesture.

On modern browsers hardware accelerated scrolling has implemented.

Using animationFrame for a smoothest and cpu-saving scrolling. (when browser supports)

Warning for IE6 users (why do you uses IE6 yet? Please updgrade to a more stable and modern browser), some feature can't work for limitation of the browser. Document (body) scrollbars can't appears, old (native browser) one is used. Some issues with IFrame scrolling.
