Added a step to clone left side content to right side as an alternative way to generate fullscreen slides. CSS hides/aligns potentially overlapping content.

In the html markup, tag the frames to be cloned with classes like so:

<div class="ms-section third ms-fullscreen-left" id="left3">
     <div class='ms-fullscreen-content'>
         :
     </div>
</div>

<div class="ms-section third ms-fullscreen-right" id="right3"></div>

class "ms-fullscreen-left" is effectively a do-nothing class, but it gives a visual indication to the developer that this content is going to be cloned across the whole browser window.

Thank you for this plugin - it was just what I needed when making an online sales brochure.
