For relationship fields, there is an “Elements” section with Featured Image, Post Title, and Post Type listed. It would be really cool if there was an option to show the respective category as well.
For example, my company runs two annual conferences and so I have a custom post type of “Attendees” with taxonomy called “event_code” and categories within this taxonomy called “event_a” and “event_b”.
If my relationship field was able to display attendees AND say what event code they are assigned to, that would be a huge help for the team of people that manages the site.
Just an idea, but theoretically looks like something that could be implemented with ease.
