While this is a great update, I'd agree with the others commenting here that there are more features to both add and refine than just altering the leveling and scaling, if only for the QoL for the 1.0 release;
Although the NPC "manager" is in the game, the only aspect it lets you manage being whether or not they show up in-game makes the feature seem woefully underdeveloped compared to other aspects of the game. Not to mention, there's no way of even previewing the NPC you're toggling, making it a crapshoot whether you're toggling the correct NPC unless you go out of your way to learn their names by toggling everyone BUT them. Giving us an in to the character editor from that screen would solve the problem, and another too, because there's also currently no way to edit NPC's you've made without going and digging through the files to delete them so you can recreate them from a saved preset. But then you run into ANOTHER problem while you're recreating them, because you don't actually have fine control over the color and pattern of clothes in the NPC editor, you have to cycle through them until it randomly generates the color you want, if it can at all, because it seems like certain clothing slots are hard locked to shades of certain colors.
Can you see what I'm talking about? Overall the game is great with the core gameplay loop being so solid, but I'd encourage the 1.0 release of the game to have a smooth gameplay experience at all levels you can engage it at, especially given that the NPC editor is a major hook for replayability.
