The iPresent It window allows you to manage the presentations to be converted to slideshows. Use the + and - buttons to add and remove presentations from iPresent It. Removing a presentation will also ensure that the slideshow is removed from your iPod the next time you sync.
A blue bullet will appear next to a presentation that needs updating on your color iPod. Either the presentation has never been converted into a slideshow or you've made changes to it since it was last converted into a slideshow.
Clicking on Create Slideshow(s) will cause iPresent It to convert your presentations into slideshows.
iPresent It also allows for any PowerPoint, Keynote or PDF document to be dropped onto it (or its Dock icon) for instant one-time creation of a slideshow for that document. Note that the presentation will not be added to the list of presentations. To do that, drop the presentation into the list of managed presentations.
You can choose between creating slideshows for presentations or simply viewing on your iPod. Selecting Optimize for iPod Viewing ensures that the slides use all of your iPod's screen. This means that the slide contents are as readable as possible, even on an iPod nano. In addition, the slide resolution is maximized to ensure effective zooming when viewing the slides on an iPhone, iPod touch or PSP.
