Fantastic tool, really like that the scope position is shown real time.
It also rescued my horizon file (which registered ACP installation seemed to have toasted) from The Sky back to ACP the easy way.
One big annoyance however is the *always on top* of all windows. This should be selectable. Despite my 30" screen with 2560x1600 rez, I had to keep moving the window to see others.
Cheers
