This is the main thread
for my Calibre Copy Cover plugin.
It won't help you apply all the Kindle hacks you need but it will send copies of your selected Calibre covers to the correct Kindle directory with the correct filenames, size & format so that the Kindle screensaver hack can use them.
Its main use is if you want to use a selection of Calibre covers as your screensavers, i.e. not when you want to use cover of latest read book.
