I've just started using Publisher and one of the things I'd like to do with it is take existing PDFs and alter them to be more useful to me. I've opened a PDF and saved it out as 100 page chunks. I'm very pleased with how well Publisher has handled the import - it's not perfect, but it's very serviceable IMO (in my experience it's hard to find anything that can import PDFs into anything remotely useable in terms of an editable document).
One thing I've noticed is that there doesn't seem to be any text flow (I have "show text flow" checked and Publisher isn't showing me any lines between frames) . I think I'll need all the text frames flowing if I'm going to make the changes I want (TLDR version is I want to change it to a web/landscape orientation, as well as clean up the text/fonts, then simplify the overall layout and design) and have the document hold up, so I'm hoping there's a way to do this automagically - basically tell Publisher to just go through the document page by page and flow each text frame to the next in left to right order.
