Works as promised, room to improve – Duplicate Contacts Manager Review

This app generally worked as advertised, eliminating duplicate contact entries. There are however numerous areas for improvement. It lacks a user manual. The controls are intuitive, but when you are potentially losing contact information it is nice to be sure what you are doing. It could use more user controls over what it does, e.g., when to scan for duplicates, what types of scans to conduct, field-level controls when reviewing individual merge records. There is no undo feature. When I did a mass duplicate removal the app appeared to propagate a photo thumbnail from one of the early contact entries to other records that had no photo. It also LOSES INFO when merging, such as data in the Notes field.
