Audiovisual Presenter is free software that helps to organize powerpoint and media files for conferences, churches and events. It allows you to store the order of presentations as a list with a description and date that can be loaded later. And once started presents a list of all slides so that you don't need to close down one presentation in order to start the next. It also presents the slides as lines of text with thumbnail on hover which can be easier to find the right slide than trying read the tiny text that appears on PowerPoint's presenter view.
