<p>Hey,</p>
<p>One more thing I thought of, is wehn previewing a powerpoint item there is a substantial delay between telling it to preview, and it appearing. In this delay, i'm never quite sure if I've clicked it properly or not, so it ends up loading several times. I expect this only happens on presetations which are image heavy. Would it be possible to add a progress bar to show that it is loading? Of to generate the prievew images before hand so that it loads quicker?</p>
