As in Microsoft Word "Track Changes" functionality, I need a development for an Add-In for tracking changes in Microsoft PowerPoint. Currently Microsoft PowerPoint lacks of this functionality.
Please review Microsoft Word "Track Changes" functionality to work in a similar functionality but for Microsoft Powerpoint.
Here I include a video link so you can review the functionality: [url removed, login to view] It is needed the same functionality but for PowerPoint since 2003 version to 2013.
The code will be needed at the end of the project as also some encription and security to avoid copying the application is needed.
