New Features in iMovie '09

I was familiar with iMovie '08 and the new laptops that my students were working on had the '09 version.  We didn't have time to explore or look for any new features in '09 but I have learned about a couple of neat ones to share with my students this year.  One is called "greenshot" and the other one is "a picture in a picture."  These can be very exciting features for my students to use!  I am ready for school to start so that we can begin; well ALMOST ready! Now I have got to go try these new features out in my own creations.  Off and running!
