I'd argue that the main navigation should be a static navbar that floats over the content. Rather than a scrollbar, a set of options (back, top, next page, etc) should always be accessible. With that, the scrollbar as it is should be fine.
Yeah. But that has to be a browser feature than something to be expected from page itself.
It would be nice if I could swipe from right end of screen and that scrollbar then allows me to fast scroll to some position.
