Sorry, produced a jumbled mess with text from the two columns scrambled together.
Might help if I understood what the unwrap is, but this didn't do any good. In fact, I got worse results on my test file with .05 than with .45 (and .5 was no better. I wound up trying that via accidental typo).
As I said, at this point, I may be stuck with extracting text to a file to be put through Calibre and am trying to figure out my best intermediate format (.txt, .doc, .odt, ????), unless someone has a better idea. Some of the files I want to work with are pretty big, so while I can put up with manual editing if necessary, it's not exactly the preferred option
.
To give you an idea of my ability level in this area, I barely know what a CSS *is*, let alone how to tweak one.
