Instead of a the plain appearance of a EntityHeaderController, make the top icon bigger and use the same circled style as the choices in the list. Also highlight the current icon in the list as selected, even if it is the default for the mode type.

(Both of these changes also line up with the "new mode" fragment that is incoming).
