Hello, a long time ago I jailbroke my Voyage via serial and everything worked out fine. Currently I have Firmware version 5.8.7.0.1. I have some issues with my buttons in KOReader, I have read the issue was closed on the thread but couldn't really understand what the fix is (anything with if you start koreader in KUAL , you should flip the page (which page?! :/) So the buttons work). Maybe an fix is now provided

I would appreciate any help there
Now a management thing : I have seen many use Calibre to manage their collection. I use mostly my books on either Kindle or phone (I get all my books from my phone). I have an sync app on my android to upload my new books to my Dropbox, so I can sync it via cloud storage on my Kindle through koreader. Is it possible to manage/sort everything through calibre but with my Dropbox or do you guys use any other way ? Calibre would mean manage everything from my computer which would be fine but not ideal
Thanks for reading, have a great day and stay healthy
