Wow! Just wow! New version looks amazing! The last version was great, but the improvements blow me away. I'd love to be able to try out the beta version, but I'm not sure how many bugs I'd find... :-P But, if you need more people to just try it out, I'd be glad to help out!

Just watching the video, I thought of a feature I'd like to request: the ability to put camera snapshots in a sketch. It almost looked like you did this when you went in to the physics sim, but it was hard to tell.
