There are more than a few books/resources that, in my opinion, lack working footnotes. What I mean by that is this. Although a "good" book has a footnote it does not allow one to click and go to that book. That's frustrating because if you want to do further research/reading you can't click and go.
There is a workaround to this. But, it involves copying part of a quote and searching your library for it.
Maybe you can't footnote a non-click-and-go footnote, and short of adding a Note to the quote I wonder if a "self-inserted" footnote beside the original one might be possible.
Just a thought.
