Please make it possible somehow that a "height value limit" can be set, which is to say that when raising and lowering the terrain then it cannot go below or above the given limit. Example: I want to lower the terrain, so I am just painting on the map with the Lower Terrain tool, but I don't want my terrain to go below 10. Setting a height value limit to 10 with the option "do not go below" would make it so even if I use the Lower Terrain tool on the hexagons whom heights are 10 then it would remain 10... until I change the new height value limit. Could be used with either "do not go below" and "do not go above" options. Thanks!
