My ordinary practice is to put all the fixed statistics for an NPC into the character sheet, but track their variables on the token: red=wounds, green=shock, blue=possibilities for reality-rated NPCs and number of creatures for mobs. I use the custom token feature to track stymies, vulnerables, aiming, etc. I'll usually create custom macros for the NPC attacks and damage that can be rolled without opening the NPC sheet. Works reasonably well. It certainly moves the game along faster than doing everything manually. I am hoping the Threat tab will display a compressed stat block much like the 5e sheet does. Easier to reference and get rolls off of it. But I'm sure Gigs has his own ideas, and they are probably going to work great, even if they aren't what I'm hoping for.
