The OM Master Slide pool is expanded further -- with up to 58 Master Slides in the Pro/HD version -- including more variations on popular layouts from the OM 2 release. The theme also features a range of new layout options designed to make the theme more flexible in the new Keynote '08 architecture. "Now built entirely with native shape objects and image placeholders, you can change the stark white background to a color, gradient or photo with a simple change on the Appearance Inspector - even change the colored panels and accents on the master slides to better match your corporate palette, or create your own layout variations thanks to the ease of the new shape object approach."
