I've grabbed this and a few other of your books - thank you very much.
Running marked:epub_unused_css_files (via Quality Check) shows up e.g.
Fifty Orwell Essays / Orwell, George
Unused CSS file: OEBPS/page-template.xpgt
Quality Check says these files can be "safely removed." However I'd like to check; I saw what you said here: https://www.mobileread.com/forums/sho...d.php?p=744547
I read books on my phone with moonreader and the headings that you don't want shown are shown. It's no big deal for me and I'm sure if I had a decent ereader I'd be fine.
But can I really delete the "Unused CSS file": OEBPS/page-template.xpgt ?
Or have you put it there deliberately to sort those pesky visible 'invisible' headers?
Am I making sense?!
PS. While I'm at it, these show up too. I'm guessing that they are harmless and there as an option if I want to make use of them? ...
