title_body: how to add page-map.xml in Sigil? I understand that ePub2 standard does not include page numbers, but ADE added a non-standard extension which may or may not work on an actual reader. I would like to try to use them, but I found a problem. 
  MobileRead Wiki says to add in content.opf a reference to an xml file, usually called page-map.xml. Sigil, as of version 0.9.6, recognizes and updates an existing page-map.xml, but I don't know where to put it (and how to put it in, short of renaming the file in .zip and adding it with brute force).
  
  What should I do?
upvoted_answer: Right-click the Misc folder icon and select Add Existing Files...
  (You'll also have to manually update the .opf file.)
  
  BTW, Sigil won't automatically update this file.
