Well, I personally am going to be making some form of an organized binder for DMing. I figured that while I was in the process of organizing this I would share it with you and look for ideas. This is not meant as a player aid (like power cards), but instead a DM aid. So far my list is as follows (short, but only until I add more):
NPC Name List
Business Name List
NPC Mannerisms.Quirks Table (DMG pg 186)
Player Handout Section (organized by session/adventure)
Campaign Notes
Attained PC Gear (includes purchased and found items, usually magic/rare only)
PC Stats Page
Conditions Page (list of Conditions effects)
Combat Crib Sheet (turn sequence, bonuses and penalties for things like cover and charging)
Spare Character Sheets
XP Table (DMG pg56)/ Difficulty Class and Damage by Level (DMG pg42)/ Fall Severity Table (DMG pg 44)/Treasure Parcel Table (DMG pg 125)
Maps (At least one map of each of the various terrains: Dungeon, Cave, Underground, Ship, Forrest, etc.)
The basic concept of the above is not to decrease time in campaign creation/encounter building/etc., yet rather it’s purpose is to increase the speed of gameflow at the table. The point is to stay out of books when looking up common things (like conditions) and staying away from those “umm” moments as a DM by having things “prepared” for when PCs do the unexpected.
The idea is to keep the printed resources to a minimal amount for both ease of reference and cost of printing. Pages are required to be useful and thought provoking. For instance, a list of names should inspire creativity for other names. I personally don’t like the idea of random treasure or random encounters, so those won’t be included, but to each their own. I also have my players track initiative in dry erase, so that could be a page that others might require but won’t be included.

The order of the things above is definitely jumbled, but I’m off to bed.
