Dependency inspector

Dependency inspector lets you check dependencies related to the field, variables and pages. Once you click on a field and check it with the dependency inspector, or find in the dependency inspector dropdown, it will show you a list of all fields with dependencies that are affecting the selected field.

If you expand one of the fields, you see all the dependencies on that field that have your selected field on it. It also highlights your field so you can easily spot what is happening to it.
