Hey! This is a very good suggestion!
I long wanted to add a second screen in the present mode to display presenter-only information, but this is not so easy to do. I guess a good starting point for PySide6 would be: https://stackoverflow.com/questions/66986295/how-to-create-a-video-player-with-2-windows-with-the-same-video.

On the other hand, we can just add information to slides using self.next_slide(info=""""), add it to the config file, and display it in either present or with RevealJS.

I'll see when I have time to work on that.
