This is an absolutely SUPERB idea that I will certainly pass along to everyone at my college!
My question: Once a user completes a challenge, and the Ribbon Hero pop-up shows, could you add an option to allow the user to simply continue playing with the current finished project?
Reasoning:
1) The pop-up occurs right on top of the finished challenge often covering their final creation.
2) For me, I just wanted to keep messing around with the tools I just learned.
Can you add an option on that pop-up that says "Keep playing with current challenge project", (or words to that effect?)
Make sense?
Thanks again, this is simply brilliant just like Christopher Dawson of zdnet says!
