For the look or for use when you don't have enough time to stick around and make sure someone else finishes...Or don't buy them :P
Come on, people. It's a free app, and one that is maintained and updated regularly, loved and used by many people...So many people asked for these tools, but they didn't have to give them to us - yet they did. They're not going to be loved by everyone, so if it's not for you, just don't use them.
I, for one, love to see things happening to the game. It's exciting! Any changes you guys are willing to spend time on I appreciate, whether or not it's something I'm going to use personally.
One thing that would be nice, for the machines that seed (or whatever) 2 crops at a time, and for the feature that allows you to plow 2 at a time, it would be nice to be able to do two in either direction, not just left to right. If that doesn't happen, I'll live
but I'd love you guys so much if that was available!
