As a developer you have the option to pass `--skip-js-minify` to `appc ti build`. I think it should be unminifed by default, and only minify for production versions. There is no real benefit besides a smaller app.
The disadvantages however are:
- Harder to debug your code from Titanium error messages
- Slightly longer build time (havent tested how much)
I suggest inverting the option to `--minify` to minify a development version if you want to. Not passing this option will not minify it. Production builds should have this enabled by default ofcourse.
