This isn't really one for GitHub. Just interested in others opinions.
Seeing as you can Sandbox mode on a new source file, shouldn't the new source file maybe contain the very basics needed for Sandbox mode like these 3 lines?:
If you're new to AppGameKit and want to test something quickly and don't include those lines yourself the Sandbox mode opens the app and then closes as there's nothing keeping it running so you can't tell what just happened with whatever you were testing.
