Rearranging Files in GAS Project (Restricted)

Gists Introduction Recently, I have introduced a GAS library and a CLI tool for rearranging files in GAS project. Those are RearrangeScripts and ggsrun. Because today, I found a new way for rearranging files, I would like to introduce it although there is a restriction. By the recent Google-update, users become able to create folders in GAS project. The new way uses this. At first, please see the demonstration GIF animation.
