It's time to update your Blender Project Starter/Manager Addon. The addon has been renamed ONE LAST TIME to Super Project Manager.
Along being a part of the Pidgeon-Tools family, version 1.3.1 has multiple fixes, improvements and big new features, such as Folder Structure Sets or the new Project Rearrange Mode. If you already downloaded the addon, you should definitely update it to the latest version. If you have some amount of money left, a donation via PayPal, Gumroad or BlenderMarket is really appreciated.
