So I must first say that the new underground dungeons look awesome!!! Very nice for a first release. There are some improvements that I think should be made. Not sure how difficult this is to fix in code but something to consider
Entrances
So I've noticed that with caves turned off, there's no way to really discover dungeons. At present there seems to be no ground access... Trillnar came across something interesting but the more I look at it, this seems to be a bug. It appears to be a staircase room sticking out of the ground:

I was hoping to see some kind of surface structure in the grassy fields or maybe a standard dungeon entrance on the side of the mountain or perhaps something more decorative on the side of a mountain. A standalone structure in the middle of a field or obvious straircase like below might work:

Something like this but perhaps not as fancy would work for fields, jungles or maybe even a swamp (whenever that biome comes):

Depth
So I've surprisingly found lots of dungeons spread about and spawning from just below the surface to just above hell. It leads to some interesting effects. I feel that the deeper you go, there should be less individual dungeons and they should all be part of a massive connected structure. Smaller dungeons should be closer to the surface. The massive underground complexes deep in the earth should be like the strongholds and rare (but certainly more than 3 in a world).

Visibility from within Caves
I'm sure his along with anything else I've mentioned can be improved. In the first one, entrances should be closer to the bottom of a cave, not so high up. Or perhaps add a different type of entrance face for this scenario. In the second one ofcourse, the outside of the dungeon should not be visible passing through a natural cave opening. Simply padding the dungeons with stone might help this or add additional structure in this scenario. Perhaps a room type with wooden stilts supporting it as it passes through the cave tunnel. Perhaps windows with iron bars in the room to look out would be appropriate in this scenario.
