Be Aware of the Curve
Very powerful, easy to use, difficult to learn. I see a lot of people pulling hair on first contact. The User Guide and Reference Guide are modestly helpful. The Ctrl key gives help on UI control elements and is a help. The tuts and Google Search are most helpful. I am a novice but I am very impressed with this tool. If it were as easy to learn as it is to use I'd give it 5 stars, probably deserves 5 anyway.
