Various bits of PHP / HTML to customize this theme. All code goes in custom.php included with the skin unless otherwise noted.

1. Remove the Roboto font

remove_action( 'wp_head', array($GLOBALS['thesis']->skin, 'themedy_inline_scripts' ));
add_action('wp_head','themedy_inline_scripts_custom');

function themedy_inline_scripts_custom() {
    echo "<link href='//fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>";
    echo '<!--[if lt IE 9]><script src="//html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]-->' . "\n";
}

2. Create your own Smooth Scrolling Links

<a data-scroll href="#testLink">Click this Link to</a>
<span id="testLink">Scroll to Here!</span>

Change the #testLink and the text to what you need, the text between the two span tags can be left blank if you wish.
