It would be amazing if the Library could keep track of where a specific asset is used per document. Sort of how the links panels work but in a broader scope. So when you look at the asset it says how many times it is used in other documents and when you get info for the asset it would list the specific documents it is used in. Like many others I am sure when we are designing a new piece we may download extra assets, or we update a document and change assets to update the look. This would be helpful when we want to "clean up" our libraries we can see right away if it is used somewhere to help decide if we want to keep it or archive it. As a bonus it would be cool if it could also display if the asset was once used in a document and list it. So it would portray maybe by Icon or Color the info as Currently Used or Previously Used and then when you get Info it list them.
