This program has 5 different staredit modes. Classic, P12, Base, Alternative, and Special. Each mode has different purposes. Special mode can allow you to place units basically anywhere. However, none of the modes can allow you to stack units and other stuff. It has a built in color tool. It lets you have instant upgrade. Allows up to 255 upgrades.
