Hi,
The mapgen settings are not user-friendly. Could we add more understandable settings like "ocean depth", "steepness", "mountain shape (smooth -> sharp)" etc. that when tweaked, change some noise parameters ? Many people ask for bigger mountains, deeper oceans, smaller / larger rivers, smoother slopes… All of this can be done with mapgen parameters, but that's very difficult to find the good digit to change. But this system shouldn't substitute the old ("advanced") settings.
I'll probably test this idea on Lua Valleys Mapgen to show what I would like.
