Thank you for your Computer Science work on Khan Academy! I tech my kids using your system for several months now, and I am very happy! :) Would be great to be able to change the rendering size from 400x400 to something bigger, may be even having a splitter in the middle, and deciding how much you want to use for the editor and for the program :) Happy New Year!
