That last post was a non-answer while I browsed the rules to see what I would want..
summary of new edges / powers / hindrances / Perks - although the only new hindrance is obligations, and I already voiced out that I didn't read it fully..
I think the skill applications pages could be made to be a quick reference for, say, quick reference
Field Requisitions (and maybe loadouts to some extent)
Common gear, and I'd put weapons on the outside for players, maybe both on the outside.
Spytech / SUD summaries. these could be player accessible on the outside, too.
A few of the mission generator tables.. Location; Global locations; Enemy Agency; Agency Purpose;
I'd make the lingo a player handout - 2 sided.
Other than that, there are standard SWD tables to include - incapacitation, Fear table..
