Am I using this field? Where am I using this field?
You no longer have to wonder... Inventory will show you exactly where your fields appear!
Viewing the Field Inventory
Once the plugin is installed, view your field inventory by going to: Utilities > Field Inventory
Managing the Field Inventory
After determining how your fields are being used, it's possible to then delete or edit those fields. Or you can "Edit layout" to change how (or whether) the field appears in that layout.
