Just a quick suggestion here.
Would really like having world generation options, just a couple things would make me happy. c:
Option to change terrain type (ex. valley or mountain types) to essentially have more or less flat spaces. Since I would like to have more open flat areas.
Changing the height of the height differences? As in be able to change how thick the different levels of the map will be, like the current style is high enough to make 3 mine shafts (I just call them blocks for the height). So you could pick how many “blocks” high your map layers would be.
This might become an option when more biomes and all that is released. Or perhaps some of the biomes will have different elevations? Only time can tell.
