I don't see what that has to do in the Suggestions Section.
Anyway, it is, especially for mining, a great feature(Especially considering that it is one of those features not influencing the Game Balance at all-just making stuff easier, saving time going trough GUIs, without actually making something a different for the theoretical Computer playing Computer Games I just invented.)
The Chainsaw, on the other Hand, may be problematic when felling natural diverse forests, since you will have more Saplings then you can plant, but with different types, selecting may be easy.
Anyway, a great feature anyway. Kinda.
Also, kinda is the new also. Kinda.
SPAm!
