I'm looking for a jQuery plugin which changes the standard scrollbars to those invisible ones only visible during scrolling and then fading away. This is probably best known from mobile devices, the new Mac OS X Lion browser, or the facebook notification area / chat bar.
I need this because when the scrollbars are always shown they take too much space.
Has anyone used this? I've found some examples for styling scrollbars but these are neither invisible upon loading nor they fade away after usage. Additionally they will not overlap with the content but instead reserve their space from the content area.
