This only processes the droppables list when the mouse stops moving for a split second (100 milliseconds in my example below), making dragging perfectly smooth while the mouse is moving. Feel free to tweak the timing to your taste by changing the integer initial value of this.mouseMoveTimerValue, or by changing the timeout values from 50 to your preference. NOTE: If you use this approach it is best to include a hoverclass for your droppables (so they become highlighted or otherwise different when activated)... so your users know for sure that it is safe to drop. This is the only issue...
