You can easily copy the theme settings you set with the theme editor from one store version to another. This makes it easy to develop the theme in a hidden development store version, and easily pass changes to a public version.
Copying will irrevocably overwrite the target version settings.
Be careful when choosing the source and destination versions of your copy, especially if your online store has versions with different themes.
The theme settings for the target version are now identical to the source version.
