I just got a Kindle recently and purchased an ebook with no cover, which irritates me like hell. After jailbreaking it, I added in a cover through Calibre, while simultaneously (and necessarily) converting it from AZW to mobi format. However, I find I lose a lot of the formatting. Any idea if there's a particular way I should set Calibre up to avoid this? I've had a look at the calibre help guide but, to be honest, I'm a bit confused, so I'm hoping someone here might be able to tell me if there's any simple and easy way to stop the formatting/font size/indents/spacing etc from changing from the original Kindle file.
