But, if you wish to use calibre to manage your collections, here is how:
- Jailbreak your Kindle
- Install MKK to authorize non-Amazon kindlets
- Add the Collections Manager kindlet to your Kindle
- Use the (Touch/PW1/PW2-friendly) Kindle Collections plugin for calibre found here: https://www.mobileread.com/forums/sho...postcount=1760
It only works on firmware =<5.4.2.1, see this thread to downgrade (if necessary):
