Thanks, David. I'll check these discussions.

But maybe I must never update the KoboTuchExtended plug-in or remove it?

BTW, the code it produces is rather ugly, compared with the clean epubs I build but the display on my new Kobo Glo is nicer than that of pure epubs.

The very notion of "sideloaded" books is quite strange to me, as I never purchased one book from Kobo in five years, and I'll never do it. I simply cannot bear the thought of reading an encrypted book, to think that for the sake of a merchant, I must suffer this humiliation, keep the sooty shadow of commercial interests over the pleasures of the mind...
