Could be cool to make a cave generator that has more vertical stretch. I.e. more vertical drops

I put this here because #2 is very full already

I was working on a custom cave generator for a separate mod. It offers more consistent caves (which almost never end); while it's rather repetitive at the moment, it could be made into a fantastic underground experience. You can define noise for tunnel width and height to get some fun dropoffs. Might be worth thinking about.
