 **Use a version control system:** Please consider using a version control system like Git to track changes to your code before running the formatter. Even though we already use the formatter ourselves at work, GDScript is a complex language and a formatter needs testing on all possible syntax combinations in the language to ensure the output is rock solid. There can always be edge cases or less common syntax that may not be handled correctly yet.
