Some breakages:
* PageUp and PageDown doesn't work.
* Home and End doesn't work.
* Long-clicking the scrollbar doesn't work A: Should react immediately, not on mouseup.
* Long-clicking the scrollbar doesn't work B: Should rapidfire (like with holding down PageDown).
* Middle-clicking the scroll wheel doesn't bring up the analog-ish scroller floater.
(Using Chrome on Win7)
It doesn't matter whether it breaks the web. It also shows new ways of thinking.
Dont forget that whatever is currently the "rule" is always in flux.
I for one hope that people will continue to "break the web" like this.
About the middle-click scrolling thing, I've disabled it for now since there doesn't seem to be any way to actually make it work with the custom path.
Also, please note that this is a very experimental plugin and should probably never be used on anything else than a personal site or presentation.
... for the sake of preserving the status quo of default scrollbars, no less?
Come on.
The idea might be good -- most people are right-handed and might have better response times with their right leg when it's straighter. But there's too much inertia in the current convention, and the change can't be made incrementally without creating serious risks.
