MUST HAVE FOR DUAL/MULTIPLE MONITORS

Apple provides the handling for multiple monitors but not for wallpaper. It is a super app that makes life easy for anyone who wants the monitors to look perfect!
Make shure you have adjusted the position of your monitors in system preferences correct horizontally AND vertically. Then it is a snap to get perfect results.
Thanks for the super app!
