The UX WG is proposing a redesign that includes this goal of letting folks more easily control the order of authors, although we take a different approach since we also want to arrange child fields in ways that make it easier for depositors to tell how child fields are related to each other.

I was just made aware of this GitHub issue when @g-saracca mentioned it in #514.

I'm trying to have the redesign reviewed for technical feasibility, before iteration continues, followed by testing where we'll start learning how well it works for different types of users.
