Sometimes you have a certain widget configuration that you need to use over-and-over again. 
Widget Favorites provides a way to save a widget instance by name to identify it later 
when loading the favorited widget instance into another widget.
Another way to look at this plugin is that it provides (non-automatic) revisions for widgets.
Note that this only adds functionality to widgets managed in the Customizer.
