The epub export isn't a bad bug. I don't have my notes with me right now. As I recall, it's how the graphics files are named in the epub manifest.
Every once in a while I think it would be cool to be able to copy a ruler. However, that's a non-styled way to get the job done. Better to set up a paragraph style and set the ruler there. Then you have one place to change all instances.
Hi Amontillado. I would greatly appreciate your insights on getting Mellel to export correctly to ePub. It does not work for me. The graphics are missing and spacing is lost.
