Managing collections this way doesn't work for me. In calibre, all books are careully assigned to collections (in category i've created), but in Kindle there's nothing. Or rather, there are these collections - in "all" category, but they're all empty. In category "downloaded" i've created collection "test".
Now - in any category I can add only Amazon books; it's the fact I know about - so there's 3 "user guides" I can choose from. It's not what I wanted...
I have many books not from Amazon, that I uploaded from computer, for example - papers from my studies, whatever. What can I do to add them to collections? My device is jailbroken, so every method should be fine. Another problem is, that my firmware is 5.7.2.1 version, so I can't make use of most things from dev's corner, like "Collection manager" from ixtab or sth like that...
Any help?
