Export or copy/paste sections more easily

[pmackim]

I've been using Storyist as my main writing tool for five years, mostly syncing between an iPad and iPhone. Fairly often I want to send a section of a longer work, for example an excerpt of a novel to a writing group for feedback. On iOS the select & copy process is tedious, particularly if you're trying to select twenty or thirty pages. Would be great to be able to copy a whole section of text from the index card level (not what's written on the card, the whole section of the novel that is represented by the card). Exporting from the index card level would be somewhat useful, too, maybe.
