I have a site where there are 5 pages that are similar though each needs different filters on the same feeds.
Would be timesaving and would easily be able to maintain consistency (without going through all the display and customization settings) to duplicate the widget and then only have to change the filters on each contributing feed.
I’m sure there are other use cases as far as once one has a favorite ‘universal’ style one can easily duplicate. Or in my case, being able to save a style in a project or at the account level to use across apps.
