Hi
To report success.
I did not use Collections. So, using the Kindle PW3, I created a Collection and named it
Divers (Miscellaneous in French). I refused the offer to synchronize and the Kindle told me I had three user manuals under this name that I could have selected. I did not add KUAL to this Collection.
When the Kindle resumed, I could see on top of the list
Divers (tagged as COLLECTION). Right under it, in number two place, KUAL tagged as DEV (see screenshot below). And under it all the PDF, sorted by date, the most recent on top (and not by alphabetical order.)
This is surprising but I find it convenient, more than the previous situation.
As I did not find how to recompile KUAL, I will make do with this solution since the most important item for me is KUAL and since I read the PDF only with Koreader.
Thanks for this workaround.
