Been using this mod for a good deal of time and it really delivers as advertised!
That being said, I have noticed "some" stuff:
-I came upon a very small (3 dis-jointed tiles) Stone area that didn't get marked.
-When you add your own label to the icon, it makes that icon YOURs and when you re-run the mod, it creates a new one under/on-top of it. No biggie and probably better that way.
Great mod!
