This is used in h5ai. I find these views more useful that scroll bars. Its amazing what can be done inside the browser these days.
> jQuery.fracs determines the fraction of an HTML element that is currently in the viewport, as well as the fraction it takes of the complete viewport and the fraction of the area that might possibly be visible. It also provides the coordinates of the visible rectangle, absolute (in document space) and relative (in element space).

At first I thought this was kind of overkill for such a 'simple' function but the example of Github shows how important effective presentation of a file list can be. To the average web user the default Apache listing can look 'broken' whereas I would have no problem directing a client to the URL of an index that looked like this.

Personally I'd just stick Varnish in front of it and keep using the webserver that I've always felt comfortable with, Apache.
