nit: reorder so that ChromeTabbedActivity and ChromeTabbedActivity2 aren't split
up. Maybe put this below MultiInstanceChromeTabbedActivity?

Done.

TabbedModeTheme uses a 9-patch with a toolbar as the window background (set
during app startup before any Views are drawn). This activity should probably
use MainTheme or FullscreenWhite for now.

              choose the first MediaRouteController that can play it, so the order of the list can be important.
              The most specific MediaRouteControllers should be listed first, followed by more generic ones.
