I think it would be nice to have a calculate area button. That would calculate acres in every layer your working in not just the main farming layer.I believe the define object button only calculates acres in the main farming layer.I dont mean change anything with the define object button. But have a completley seperate button just for calculating acres. I saw all the new features comming in version 4.4 look great an I am looking foward to them. Keep up the good work.
