For those reading their premium ebooks through Kindle stuff (for me, specifically the Android app on a Nexus 6), are there any optimal settings to use in Calibre when converting to end up with as high quality of output as possible?
I tried outputting to Mobi and found some setting about not converting images to jpeg & leaving them as is (think it was with the output device a generic tablet?), they are big enough to read everything so I think it is okay but if there's options I should be using I'd like to know about them.
Also, I lost the cover somehow after emailing it to the Kindle address - is there something I'm supposed to do in Calibre to keep the cover visible in the Kindle app?
I know I can use other ereader software, I just prefer to keep everything in the same place as I'm buying my non J-Novel light novels from Amazon (after Play Books region screwed me after the first few volumes of Re:Zero & Konosuba)
