As a knack app builder I would like to see a feature that shows where each particular field is being used as far as which pages the field is on. When I am editing the app it is hard to remember all of the pages I have used the field. It would be most helpful if I could see where the field is being used when viewing the field in the Schema.
You can use this third-party tool in the meantime: Definitions
I agree this should be a native Knack feature.
