@alanjay,
I'm making an assumption here, which may be wrong, but if you're having difficulty reading the screenplay PDFs on your reader because of the excessive whitespace margins have you tried either of the following:
- Use Briss to visually crop unwanted margins from your PDF. The output is still a PDF but if the source had a TOC & metadata they should be retained in the output PDF. Briss is still under active development and the creator is very helpful.
- Use a PDF to TXT utility which can retain multiple spaces. Then read the TXT on the reader. The usual loss of italics/bold styling which happens with PDF to TXT doesn't really apply with a screenplay in plain Courier throughout.
