A feature I would love to see is the autofill of information on a book already included. In other words, if citing mutliple chapters from one book, after the first time entering the book information, it would be autofilled in any other citation from that same book. At present, this happens with the title, but this doesn't trigger an auto-fill of other fields such as publisher, location, date, etc. It would save a lot of annoying typing.
