Nit: Can fit on one line (and be just as clear) with auto:
    auto* web_contents = browser()->tab_strip_model()->GetActiveWebContents();

[Bret, 2017/02/09 00:49:49]

Done.

+    command_line->AppendSwitch(switches::kExtendMdToSecondaryUi);

Do we need/want to force this here?  Seems OK to just have the user pass this if
they want?

[Bret, 2017/02/09 00:49:49]

I felt like people who are using this suite don't care about the old version.
But I guess it's better to just let the user decide with their switches, so this
is removed.
