We need to be able to view fields (such as people and number) on the roadmap view for quarterly planning. We like a list view of all of our epics with fields such as Reporter, Assignee, etc. and number value such as RICE score. We use this to be able to have a birds eye view when planning and prioritizing.
This exists on classic projects in the ability to add fields to the card layout in backlog.
Is this something you'd consider adding?
