If I'm reading it, I wouldn't look up a note on what a "chaise and four" is, because I know what it is, and I wouldn't want to see the half page of text on it in the middle of the main text either.
In the case of this particular book, by the way, even in the printed book the notes are endnotes, not footnotes. If you have a few words, a footnote is fine, but if you have a page of explanatory text, an endnote works a lot better.
Sure and I intend to add both a footnote and endnote button to our interface in the future (currently we only have the footnote button). Based on the output format, each will behave differently.
