Identify redundant fields for deletion

It would be great to be able to identify fields no longer used in automations.

Over the years many fields get created that are no longer used in automations. These use up space for every record. Also, sometimes I hit the field limit and then have to determine which ones I can delete so I can add the new required field.

If I could run a report to identify these redundant fields and then delete them to keep my databases maintained - that would be fantastic
