public bool use_action_appearance { get; set; }
Whether this activatable should reset its layout and appearance when setting the related action or when the action changes appearance.
See the Action documentation directly to find which properties should be ignored by the Activatable when this property is false.
Activatable implementors need to handle this property and call sync_action_properties on the activatable widget when it changes.
