Hi Steve,
I just wanted to add my vote for a footnote/endnote function in Storyist. I need to write a scholarly paper based on creative work I have been composing in Storyist, and unfortunately the lack of this functionality means I have to work in dreaded Word. I appreciate that Storyist is really structured for literary media, but needless to say, for all kinds of reasons, citations would be a key, if not essential, asset to what is otherwise the very best writing software.
