Dear Kovid,
I manually insert a link to another book in the same library, the link is like this:
Code:
#book_id={id}&library_id={library}&panel=book_details
If I click (on PC using mouse) or tap (on Android) the "loading" never finishes. But "open on new tab" works instantly (lucky me). Is it fixable? And it certainly doesn't work in the Main Calibre, but I don't mind this.
