I've been playing with the conversion options but I'm stuck trying to put a cover image in the output KFX file for a while now.
Is there a way to do that?
I have been trying the conversion from an EPUB file to KFX. So far I have been successfully converting it and I can see the file and open it on my Kindle Paperwhite but the file doesn't render any cover when I'm in the Library view.
BTW

this plugin works just fine when all the conditions are met.
