Persistant highlights, bookmarks, etc in widget.

[jmgpp]

Hi guys, sorry for the basic question. But so far whatever I do on the book seems to be stored in memory only, I would like to know if the widget has any callbacks to when the user highlights a text for example. Or how is it stored in the app because I noticed that while I remain inside the book, even if I move to a different document inside it the highlight remains stored somewhere and redrawn when I go back to the chapter.

Thanks for you help!
