Epic link label visible on story in Active sprints (Work mode) when using story swimlanes

Original summary: As a Scrum Board user I'd like to see the Epic assigned to the story in Work mode (story swimlanes)

Currently the Work mode's Story swimlane setup only shows the key + summary, but it would be useful to see the assigned Epic also. Users would have a better view on the sprint if the affected epic would be shown on the stories.
