As mentioned elsewhere, the footnotes really appear as endnotes in the epub file. I can navigate on the BeBook or other ereader software from the highlighted footnote indicator in the body of the text i.e. a highlighted "2" for footnote number 2 to a place at the end of the ebook where the footnote ( now an endnote) is located. After I rad the endnote text I can return to wher the original footnote indicate is located and progress onward in my book.
It appears that the Kobo software, in its present form cannot do this.
