[Feature request] Add a speed factor to the directive

[Tofandel]

It would be nice to be able to change the speed factor

I have some lists that are very very long and the speed factor of 1 (scroll the same amount the mouse is moving) is way too slow for scrolling in those list

That'd be a great improvement

An easing would be nice as well with this feature, so if you release the mouse while dragging, it keeps dragging based on the speed when released, and then slowly decelerates

That would be some kind of scrolling momentum? If so it would make the scrolling experience more natural. +1 to this request.
