 ## FAQ
 - Should I use Calibre?
  - No. Calibre doesn't properly support fixed layout EPUB/MOBI, so modifying KCC output in Calibre will break the formatting.
    Viewing KCC output in Calibre will also not work properly.
    On 7th gen and later Kindles running firmware 5.16.3+, you can get cover thumbnails simply by USB dropping into documents folder.
    On 6th gen and older, you can get cover thumbnails by keeping Kindle plugged in during conversion.
    If you are careful to not modify the file however, you can still use Calibre, but direct USB dropping is reccomended.
 - All options have additional information in tooltips if you hover over the option.
 - To get the converted book onto your Kindle/Kobo, just drag and drop the mobi/kepub into the documents folder on your Kindle/Kobo via USB
 - Right to left mode not working?
  - RTL mode only affects splitting order for CBZ output. Your cbz reader itself sets the page turn direction.
 - Colors inverted?
  - Disable Kindle dark mode
 - Cannot connect Kindle Scribe or 2024+ Kindle to macOS
