First of all I have updated the italian translation that presented some minor errors and omissions; it is attached.

Then I would like to share what I understood until now about why only some annotated books are shown when I select ‘Fetch annotations from device’ (not much really).
The problem may be related to the matching of books in the Calibre library and on device but rather to the format/title of the books. In fact, if an annotated book does not match I expect that it will be shown in red and require manual match but not that it is not shown at all.
To check this hypothesis I made different trials sending the same book to the device from Calibre in different formats. I discovered that books in the new Amazon KFX format are not considered in the list of annotated books. Unfortunately, this is the format that most books are nowadays downloaded to the device from Amazon and it is very convenient too because it supports typographic enhancements, better speed and better navigation.
Furthermore, but here I have to investigate more, it seems that AZW3 books sent to the kindle from Calibre are recognized while AZW3 books downloaded from Amazon not or not always. MOBI seems OK.
Finally, other things that I still don't understand occur, like this:
I send a book in KFX to Kindle, annotate it and cannot see any annotation. I remove that book from kindle, I send the book in AZW3 and still cannot see any annotation. I add another annotation to the book and when fetch annotations finally I can see it with 2 annotations, but then when I preview them nothing is shown.

I still have not found a rule to understand which annotated book are shown and which not.

Well I wished to share these first findings, I will investigate more and will report but any suggestion is welcome!

Ciao,
Dario
