Feature Request: "Not In Use By Level" Filter For The Content Browser

Hey, guys. One of the filters for the Content Browser, “In Use By Level”, can obviously be handy.

But I was wondering: would be willing to create a “Not In Use By Level” filter, to add to a future engine version?

I reckon that others, as well as myself, would find it handy for deleting unused or unwanted content, in order to maintain minimal file sizes, especially on smaller/mobile titles.

Thank you! :slight_smile:
