This should be off by default. I had already played for a good amount of time by the time that I noticed that my mining site was digging more than I wanted it to.

First of all, awesome mod! I wanted to post a suggestion to CoI about this and then saw that there's a mod for it. Many thanks! :-)

Is it possible to have a "Max layers to excavate" zero so that it doesn't dig down at all? When mining the ore from a mountain, I prefer to start at surface level only and dig down later or maybe even not at all.
