More flexibility with videos (embed, unembed, file names, ...)
Usually, I do not embed videos in my PPT files, but rather link to them (they are still being played inside the presentation, they are just not embedded in the file).
This is a good feature, because it reduces space usage on my hard disk (I often need to mix and match slides).
However, sometimes, I would like to embed all the videos that are already included in the presentation, so that I can send it someone else.
Sometimes, I can imagine, people would like to do the reverse: extract all videos from a PPT file, save them on disk, and make PPT use those files (linked) when playing the presentation.
Relatively often , I would like to get a list of all the files of all the videos that are included in my presentation.
