Wow! Pretty impressive. I opened a Chess game and then went into Edit to see if I could live edit Chess/app.lisp to change the title bar name to "Chess" in the running instance, but the change only shows after I open a new instance of Chess after a Save of app.lisp. Is there any way to live edit? I'll join the element discussion. Thanks! I am a Lisper, so this will become my new playground for fun and experimentation outside of the Windows/Mac/Linux world.
