Thanks to the users of this forum

I have do to jailbreak the Kindle PaperWithe 4 5.10.0.2 and now i have on "KUALBooklet", "kual helper0.5.N", "python-0.15.N" and "screensavers hack" and work perfectly!
Now I would like to create collections and i have look for in the forum and i think the best way is "LibrarianSync", but I don't have understand if this program works on 5.10.0.2 firmware.
Can I installed it without problems?
Alternatively, how can I create a collection, preferably from a PC?
I prefer don't register the Kindle because I'm scared for the eventually update, which could create problems with the JailBreck.
Thanks
