Simple example:   $(window).mousemove(function(e){   var mousePos = e.pageY   TweenMax.to(elem, 0.35, { y: -mousePos, ease: Power2.easeOut }); }); is there any better way of doing this rather then having an easing every single time the mousePos is updated? Would be nice to have an easeInOut (easeIn when I start moving and easeOut when I stop.
