It takes a lot of time, to set the right terrains to hills. It would be great, if hill-terrains are automatically applies to all terrain, that would be higher than the origin hight. Maybe there could be an Option "Set Hill terrain automatically" to the hight tool?
So if want to make hills i could decide to set the appropriate terrains automatically. Other terrains, like snow, water or lava could be set afterwards.
For me this would bring some benefits: 1. I could better see, where hills begins. Sometimes this is not so easy. 2. Making maps would be more faster and efficient
