I agree that the field should go back to Nickname. Just because we happen to know someone's nickname, that doesn't mean that's what they'd prefer us to call them. In the database, for anyone to know what name to use, I show that in the Addressee/Salutation area - Primary Add/Sal. The Primary Addressee then shows as their preferred name on their record. I consider the Nickname field as information that we can potentially use as we get to know that person better. It's not the name to be used automatically if you don't know them very well, yet. Most people use nicknames around their friends and family, but not always in more formal situations.

If it is necessary to change the label on this field, I wish it would be "Alternate Name"...but I'd prefer it just be Nickname.  It's getting more and more confusing (and will require more and more updating of documentation) to have a term in RE:7 and a different term for RE:NXT that references the same field.  I appreciate the term Attachment rather than Media, because that is essentially different functionality.  But the rest is just confusing...particularly for staff who are transitioning from one to the other or working with both simultaneously...or for searching in the Knowledgebase, Community, or Idea Banks.  When I want to add an Idea, I try to do it correctly by first searching for the same thing already existing...but it takes longer when I have to search for "nickname" and then "preferred name" or "proposal" and then "opportunity" in case the Idea was posted before the field label was changed.
