There may be problems on the Mac OS!!!
This addon saves versions of your project in a separate folder.
Now you can better control the version of the project, and not afraid that they will be lost.
All you need is to set the time interval for saving files.
A version folder will be created in your project directory.
The file names are numbered and have save date and time information.
When creating an addon, I tried to focus on this technology in Autodesk Maya, but the Blender only improves it because of the rapid imperceptible preservation.
