Indicate on a folder in the project view if referenced assets are inside it

Indication of used count on the folder of all items inside the folder. or some other indicator that it contains referenced items. This way one can quickly see in the project window if a folder is empty of referenced items or not.

Or just an 0 next to the folder when there are no referenced assets inside the folder Then I know if there is not a zero by the folder that there are items inside that are referenced.
