Remove decorations prior to placing entities or tiles. In real life you would not build a house/road and leave the bushes below it, would you?
Small changes concerning balance, gameplay, or graphics.
Map generation and terrain modification.

This is weird ... I mean: The mod is pretty trivial and has basically no code ... will investigate in a few days - cant play on my linux box atm :(
