Fantastic tool! I reproduced my entire island on it. I'm using it on mac, and I wish I could save several files, today the tool allow me to save just one. (I can rename the file on terminal to have several save files, but it's not practical). Other wishes are: zoom out, trees and flowers. The fornitures are not needed, 'cause the use of the tool is to plan the terraforming before breaking down the entire island! The idea of a placeholder sizeable is fantastic! Congratulations!
