I’m going to add this here as it’s the only somewhat relevant one I can find.
If any type of file is used in smart module content, File Manager displays that “This file is not used anywhere.” But it is!
As with the PDF suggestion above, if a file is in use anywhere across the platform, then it should say it is and tell us where. It’s misleading and can lead to major errors during audits and clean-ups. Otherwise, instead of “This file is not used anywhere”, it should say, “This file is not used in mainstream content, but if it’s a PDF it may in fact be being used, and if it’s used in a smart module then it also might be being used. We don’t really know.”
