A family of Microsoft word processing software products for creating web, email, and print documents.
Thank you, Jakob, for bring up this topic. I have been searching around for the very same thing. Like you, I have not found a solution.
Here is my very specific situation.
I work in a corporate training department writing manuals. For the bulk of our existence, we printed all of our manuals for in-person training. Some people loved this because they could carry them around. Some people hated this because it meant lugging them around. So we started supplying PDF versions for download.
(We provide PDF versions because they cannot be edited as a Word doc could be)
Now that we are delivering almost all of our training remotely, we no longer print and only provide PDFs. As long as we are not routing our manuals to printers, we have no need for the concept of page breaks.
MS Word has excellent capabilities to create *.mht files with Tables of Contents that automatically create hyperlinks. It's great! But when I attempt to save the document into a PDF, the page breaks are there.
This is why I, personally, am looking for this. It's not just some late-night curiosity. There's a very real business purpose.
