I thought it used to be on the Configure this device: form (right click the device icon)
OK a backdoor (Calibre not running)
In the configuration folder:
Use a TEXT ONLY (like notepad++) editor on
Code:
device_drivers_KINDLE2.py
KEEP A BACKUP
Change this section to the opposite
Code:
# use author sort
# Use author sort instead of author
use_author_sort = False
