> All-In-One Chart: A single page with all the info you'd need for a game? I can do that.
Oh yay, I came here to suggest maybe doing that with the blank page 12 :)
(I ran the PDF through pdfbook2 today, but decided to hold off on printing/stapling it until I could whip up a useful back cover)
(Probably also on your list, and possibly already done, but: maybe also update the 0D0P table in the book with the update that goes to D10?)
(I also made a 2-page version of your character sheet for duplex printing. I'm not sure I've ever seen a back-and-front character sheet in the wild, but I've wanted one several times. Maybe that's just me, though.)
