I think it would be super helpful if we could create dropdown list categories from the field creation page. Previously it made sense to have that only in data management because fields were also created there. Now with NXT, you create fields in the Company/Relationship/CTA tabs within admin so having to bounce into data management is an odd workflow. Additionally, I wish it were like SFDC where you could choose to leverage and already existing category (in SFDC speak that would be using the global picklist) OR you could create a new category from the field itself (like SFDC). It's pretty rare to use the same dropdown category for multiple fields.
