This idea has been merged into another idea. To comment or vote on this idea, please visit RENXT-I-197 Ability to Sort Relationships.
Contacts and all other types of relationships under Relationships in NXT are currently sorted by date added and there isn’t currently a way to change this. The list of contacts look really messy and we would need to be able to sort them by different options, by first name or surname, by contact type, etc.
