Great changes! My wife and I conduct Lego WeDo and Scratch and camps for kids 6-9 & 9-12. Even the 6 year olds have no issues with the WeDo interface and could handle a bit more—but the Scratch interface is out of reach to all but the most advanced 6-7 year olds (top 1-2% in reading/visual-spatial). These changes look like something in between the WeDo and Scratch levels.
