Recently while working on a ticket, I had to scan through 6000+ contents in the client's content library to see how many contents have View/Edit Privacy settings.
This took hours for me to do. I could have done this in a few seconds if there was a filter to filter out the contents which has View/Edit Privacy settings.
If there are filters for Tags, Collections, Owner, Created Date, Moderators, Custom Fields and dozens more, why not for Privacy contents?
So, I believe there should be a filter for this.
