not used it in anger, but it looks very helpful, i like also the shortcut to lyngsat in the transponder tab.
i don't know if this is of interest i pulled it of the home site
Offset satellite dishes are widely spread now. When such a dish is completely vertical, it already has some elevation (~20-25 degrees). You can enter the size of your offset dish (height and width) and the program will calculate the exact elevation for this dish. The calculation is done only for dishes whose height is greater than width. Enter the size of the dish in millimeters. Here you will see the elevation to the selected satellite and the angle you should actually install you dish at (in degrees from the Earth surface).
