It’s true that the biggest new feature in Office 2007 is the interface and thus usability improvements. The new ribbon tabs change dynamically depending upon what task you are doing — yet unlike the old toolbars of pre-Office 2007 applications, there’s no way you can create a new ribbon tab in PowerPoint 2007.
That’s not entirely true though since you can actually create and edit the ribbon tabs in PowerPoint and other Office 2007 applications using a third-party add-in called RibbonCustomizer.
