I still make notation the way Gerry did, except using CorelDraw12. Hence my reluctance to make notation. :-S (That’s why this program you guys are making is going to be sooooo awesome!)
As for the arc with the 3 over it: I can’t remember if I saw that somewhere, or made it up 'cause I couldn’t think of any better way to describe it. Maybe it should be more like a straight bracket as opposed to an arc?
