Add an options / settings page

Add an option (tick box) that will allow the user to save meta to the plugin, or to their theme.

Consider other options / settings that may be helpful for working with components.

No files, tests, or admin entry points are identified. Start by locating the plugin’s existing component-management and settings code, then clarify which metadata destination the tick box controls and which additional settings are in scope. Done means an options page lets users choose plugin or theme storage and the selected setting is honored.
