Features Board: Master Features vs Features

As a user, I would like the Master Features vs Features indicator to stand our more. So many times, I go to the features board get alarmed because I'm not seeing what I'm expecting to see. After I calm down, I realize that the view is flipped to master features -- or epics, as I call them. To me, the distinction is far too subtle and I would appreciate some kind of improvement in the usability.
