Scrolls the document smoothly when scrolling the mouse wheel
Basically an enhanced and configurable version of the built in smooth-scroll. Uses some unique algorithms for smoothness and adaptive behaviour (scrolls fast or slow according to the "intention" of the user). Allows to read long web pages easily. You can actually read WHILE scrolling. Kind of like the credits at the end of a movie, but controlled by scrolling the mouse wheel. Works with text-boxes and drop-down boxes too. This version Exposes more configuration options.
