I tried it in the past days but it didn't do anything, I tried again after disabling pop up notes and now I see (on the book I'm reading it works "In-page classic classname footnotes"). Good invention.
Now I will discover what happens if the note is very very large. Some notes are chapters
Impression: in this modality the ebook seems more similar to a "real" book. I like very much pop up notes but also in-page notes are a good choice, especially on a large screen like KA1. And I like the possibility to have options.
