Synchronize footnote settings in books and number across document
Regarding using books and footnotes: I really, really wish the footnote settings were something you could synchronize when synching your book. Also, I wish there was an option to continue numbering throughout the individual documents. Currently, if you do not have your whole document threaded, it will restart the footnote numbering, so I have to set it to restart numbering at each page (or section).
I frequently have books with a dozen different chapters and would like the footnotes to number sequentially within each chapter; and it would be one less thing to remember to edit if the document footnote settings would synch across all chapters in the book.
