@lmorchard I especially loathe the way my one single action "scroll" turns into "flip to next image down" and then into "flip sideways" and then "jump to image" and then "make something move in the opposite direction from the direction I'm scrolling" and then "zoom out".

It's like someone said "Here's a box of effects. You have to use all of them at least once. Make it easy for me to grade."
