Georg,
I more or less use frames as slides and blank space to present over MS Teams (screen sharing software).
When someone in the audience has a question, I’ll copy what they’re asking about with the lasso into a new layer and make the previous layer invisible. So, by the end of a session, the resulting x-sheet will look like:
[ slide 1 ]
[ slide 2 ] –question!–> [ slide 2.1 ] –> [ slide 2.2 ]
[ slide 3 ]
. . .
[ slide n ]
At the end of the session, I can export the frames on each layer and use pdfmergy (an online pdf conversion app) to reorganize them into a single pdf file that I share with attendees.
