Visual indicator on shared items
Would be good to add a visual indicator on Document Libraries, folders and files that have been shared. It could be an active small share icon next to the item.
From the modern document library view, users will be able to identify any items that have unique permission (broken inheritance) compared to the Site permissions.
Now users can easily share folders and files or even change the permission of the document library, but it's then really difficult to track down these shared items.
