In the last week or so I've finally had a look at ST7, and I gotta tell you, I don't know about anyone else, but I am excited about this release. A lot of these additions look familiar to me.
We're going to dribble some of these features out just to spark a little interest. The first feature to "leak" is the Fixed Length Curve. You can apply a length dimension to a curve (spline) and it will act like a piece of rope. Check out this new ST7 feature demo video.
