There is a newer version: 4.6.21.ayg

/*
 * code review by Pavel Yaschenko
 * 
 * 1. No need to save DOM element (this.indicator). We can use id to get dom element. It helps to avoid memory leaks :)
 * 
 * 2. Name refactoring: change names acceptClass, rejectClass, draggingClass 
 * 						to more readable names: getAcceptClass, getRejectClass, getDragClass
 *
