Content types are an essential part of SharePoint. One issue that has been around since SharePoint 2007 is the absence of an overview of all applied content types. Why is this important? Try to delete a content type and you get the message it’s still in use. Good luck finding out where. This is very frustrating and time consuming. That’s why I vote for an overview where you can see where the content types are applied.
