Layers?

Well, if you go here:
http://www.masterslider.com/wordpress/free/
it says this:
Order slides with ease! Change the order of any Master Slides with our intuitive drag-and-drop style editor. Add and change layers, edit the slide transition and durations and other cool effects all while sipping a cup of coffee. No animation coding required.
But this layers are listed only in the paid version and not the free one. Any comments about this, please?
