Minifing the output code means faster load times for the client and less bandwidth. Visual Studio do this automatically on building a release copy of code. Debug code should not be minified or at least have the option to do it or not. See Yahoo's tool http://developer.yahoo.com/yui/compressor/

Thanks, Adam. Minification isn't as important when the code is installed on the client-side computer once instead of downloaded every time the app is loaded, but we appreciate the feedback. Definately making sure the app loads quickly is important to us and smaller code helps there. Thanks for the feedback.
