I really would appreciate a nice feature:
As I (and surely many other users) have a lot of "unused" media in the library, it would be a very good idea to directly see, if an individual media file is in use (is linked) by Wordpress.
E.g. all used media could be marked by a dot/star or something else in the media browser.
To clarify understanding of my text, I have attached a graphic in which the 2nd and 3rd media file is used in Wordpress and the others are not.
Best regards and thanks for your nice product,
