This software is used to prepare speaker prompts. The current slide along with the following slide is printed on one sheet of paper. By referring to one sheet of paper, the speaker will automatically know the next slide in the sequence. So, on one page you have the current slide and a preview of the next slide; problem solved. This small application is meant as the 'finish' of your presentation preparations, so, there are limited options to edit slides or reorder slides. Do all of your heavy lifting in your presentation application and just use this to print out your slides.
