I just tried your W2E 1.1.9 and it was a complete success.
I just made an HTML file out of a PDF text using FineReader9.
I inserted this HTML file in a tailor made model in OpenOffice.org Writer 3.2 and saved it as an odt file.
After, I began to use W2E:
I checked the metadata, OK
I checked the splitting, choose my favorite font, OK
Pressed the button and 8 seconds later, I had a nice readable epub.
I have not tried complex epub yet (images, TOC, footnotes) and will try to report about it later.
This is an awesome extension. Making a plain epub with OpenOffice.org became at last nearly as easy as producing a PDF
Congratulations and thank you so much!!
