• [ ] Move "0 Setup" folder outside of genres folder and ensure it gets deleted if "Delete Setup Scene" option is enabled
• [ ] Assuming the setup folder was moved outside of the genres folder. The genres folder only contains well genres, and this means no more hardcoded folder names in setup script.
• [ ] Implement "Sub Genres". Each genre can contain multiple projects. An additional dropdown button should be added to the setup scene.
• [ ] Figure out how to queue the editor to close and re-open once all files are done moving around
