A list of timestamps in both file menus paid for itself only on the day something went wrong, and it was in the way on every other. The entries are gone; loadDocument now offers the versions where the browser copy has actually failed the reader — newest first, one question each, and the one taken up starts under the boot flag like any other document. The store loses its reactive singleton with them.
