You can create a preset to save your current theme settings, either for security backup purposes or to experiment with other themes. You can then use the preset to "roll-back" to the theme at any time, guarding all of your theme settings.
It is also a good idea to save the default or manufacturer settings of a theme before you start customizing settings. You could create a preset and name it Default.
The presets will be stored in the settings_data.json file within the theme files. If you are a designer creating a new theme, make sure you include the settings_data.json file in your theme. When users install the theme with this file included, they will see your preset styles in the pull-down menu in Theme Settings.
To Create Presets:
1. Login to your Workspace
2. Click on Themes from the left menu.
3. You will be taken to Theme Settings
4. Check the checkbox "Create a new preset". Enter a name for the preset.
5. Click on Save and Apply.
Only four presets are allowed per theme.
