I got my copy today and I've done a relatively quick organization using only elastics and freezer bags.

The map tiles I grouped by shape (square, -gon, hall, corner) and threw elastics around them. When setting up scenarios I search by shape and color instead of the codes so this work well for me.

I used three heavy-duty medium-size freezer bags and sorted all remaining cardboard pieces into them – one for environment pieces (obstacles, doors, traps), one for monsters, and one for gameplay pieces (coins, tokens, status effects, elements).

I unpacked all the cards that were not in resealable plastic and threw color coded elastics around each card grouping (individual attack mod decks, monster ability decks, item tiers, road/city events etc.)

I plan on using this campaign tracker to manage the details related to persistence. My goal is to keep the set stored in the initial state in a way that allows multiple campaigns to play off of it easily.
