Some years ago, I saw a strange function in Open Office. I’m not even sure whether I understood it right. Two documents lying on each other with a kind of a „window“ in the upper one, so you could see both the document you were taking notes of and the document you were editing. Did I guess that right? Does there exist such a function? If so, does Libre Office Writer have this?
Thank you.
P.S. Sorry if I understood a completely different function all wrong.
