All `responsive: 'y'` did before was trigger the page reload. Ideally the plugin should keep to the width set by the user for .browser-content, and the plugin would be built around that. We could possibly, instead of having a `responsive` option, do the following:

    var widthFromCSS = $('.browser-content').css('width');
    if (widthFromCSS.match('%')) responsive = y;

Why were `filePath` and `shadow` removed?
