Currently, we have items on Wikidata that contains tons of different properties that have the subproperty "Wikidata property for authority control". I think it would be great to be able to collapse all 'Wikidata properties for authority control' so that the page loading time is faster for a person who wants to browse the item without caring about the authority control statements.

Apart from authority control, it seems to me like this would be useful for the items for countries as there are a lot of different statistics associated with a country.
