Is there any mod or server plugin that changes the map generation in Minecraft to adjust sea level?
Basically I am looking for something that will let you customize what you want the sea level to be and then it changes the water to be at that level. However it should also take into account things such as trees and beaches. So if where a tree would normally generate is now underwater then the tree would no longer be there, additionally it would make beaches at the new water level rather than at the 63 block height.
