The jspdf branch has a prototype for using jspdf which is a lot faster than the current implementation. Unfortunately jsdom/jsdom#3179 was getting in the way.
I don't know what the situation is now, maybe someone want's to have a look at it ๐คท.
I have a bunch of books in my digi4school account that cannot be downloaded, due to the fact that they are not stored on digi4school, but on another platform like trauner.digibox.com or hpthek,com -> as far as I know all books with a "plus" next to them
But these platforms appear to be the exact same as digi4school, only with another domain name.
maybe with a flag to change the base URL?
