At some point on the roadmap I think it would be nice to have a "minimize" option to force the resulting .JS files to be as compact as possible.
Obviously this would be a future feature when all of the more pressing stuff gets completed.
Just as an FYI if you run Google Closure Compiler on the currently output .JS files the resulting files are non-functional (despite the fact that you get warnings but no actual errors).
Keep up the awesome work. Really starting to have something here.
