I researched Powerpoint slide organizers for a faculty member who wanted a way to sort his slides individually and in groups.
The different organizers I downloaded and tested (using free trials) are:
- Slidewhere (http://www.slidewhere.com)
- Slide Executive (https://www.slideexecutive.com/powerpoint-presentation-library-products/slide_executive_desktop.aspx)
- Slideboxx (http://www.slideboxx.com)
- Presentation Manager (http://www.presentationpro.com/presentation_manager.aspx)
