Hello!
I own Kindle Paperwhite 1st Gen, which recently has been updated to 2nd Gen software (5.4.4). But footnotes still open in the old way - no popup (tested on various epubs converted by kindlegen). The Kindle User Guide says that "not all books support the Footnotes feature". So, back to the topic, what is "Source code for new KPW in-line footnote feature"? Can I change an epub somehow so that after kindlegen conversion the Footnotes feature start to work?
By the way, maybe Calibre can convert books properly? Going to test...
UPD1: No, after Calibre conversion still no popups.
UPD2: Oh, looks like the solution is here:
Inline footnotes - solved? Sorry for this post.
