Hyperscroll - special mode turned on with a button next to scroll that turns off scroll friction and let's you scroll into infinity (wheel keeps turning after you lift your finger).
Yeah, it takes some getting used to (the wheel is VERY sensitive to even the smallest finger movements), but when you get used to it, it's clearly superior to a regular scrollwheel. Much less finger fatique.
