[MIB.6361]

I think this is a great idea. Adventurers, Spells, and Exploits. And the Character Creation Cheat Sheet (if that's not going to be a free PDF).

I'm likely to print and bind my PDFs (I did with G:DF) anyway, and I'll probably put all of that in one book.

I'm also going to compare the helpful backs of the books to the GM screen and whatever's additionally useful from them, I may print into a separate reference book/sheet.
