Always a big fan of your stuff, and I use stuff all the time, but I came upon a small thing that I wondered if it'd be possible to add a tag for and a style for?
Sewers.
My players seem to find themselves in them a lot, and while this generator is great for a classic door kicking dungeon, it doesn't cater well to undercity running. Obviously, I have no idea how the generator could handle it, but suggestions for a "Sewer" tag: Wider corridors (3 or 4 tiles wide), Junctions and a lot of "crossroads", Ladders, A focus on smaller side rooms and less rooms overall, A more uniform water layer to flow in channels and in circular rooms.
Again, I'm sure that's a lot of work that doesn't sound appealing at all, but never hurts to suggest. Still adore your stuff
The setting I run is a modern steampunk, so the sewers I run in seem like a strange mix between modern sewer and Victorian brickwork sewers. I lay them out as long, wide tunnels with water channels in the center of walkways with small little maintenance rooms or pump rooms. Dead ends leading to ladder hatches are also a thing I do. (If only because I don't want ladders every short length of tunnel.) Important thing I do, too, is make the tunnels run to the edges of the map implying they continue (if my players want to skip through the water longer, for some reason).
I appreciate the consideration, no matter what you do!
