It’s pretty easy to check if a Jetpack module is active:

$jetpack_active_modules = get_option('jetpack_active_modules');
if ( class_exists( 'Jetpack', false ) && $jetpack_active_modules && in_array( 'your-module', $jetpack_active_modules ) ) {
      // Do something
}

I’ve been working on a plugin that needs to update the text of an object via javascript when an element is clicked. Like the rest of my plugin, those strings in the javascript need to be translatable. Thankfully WordPress makes this easy to do.

Original

Let’s say this is the script you are enqueuing:

function prefix_enqueue_custom_script(){
	wp_register_script( 'prefix_custom_script', plugin_dir_url( __FILE__ ) .'js/custom-script.js', array( 'jquery' ) );
        wp_enqueue_script( 'prefix_custom_script' );
}

Translatable

In this custom script there are two strings that should be translatable: “upload” and “remove”. To make this happen we’ll use the wp_localize_script function, which gets hooked onto the script handle:

function prefix_enqueue_custom_script(){
	wp_register_script( 'prefix_custom_script', plugin_dir_url( __FILE__ ) .'js/custom-script.js', array( 'jquery' ) );
        wp_enqueue_script( 'prefix_custom_script' );
        wp_localize_script( 'prefix_custom_script', 'prefix_object_name', array(
		'upload' => __( 'upload', 'textdomain' ),
		'remove' => __( 'remove', 'textdomain' )
	) );
}

Using the Strings

Now in my javascript, instead of simply using the text “upload” and “remove” I’ll use the variables prefix_object_name.upload and prefix_object_name.remove.

The latest version of the Options Framework has a new hook to display content below the options panel. This feature was added thanks to @Satrya, who posted a neat screenshot on GitHub and requested it.

The hook can be used to display any content below the options panel, but one cool use is to add a sidebar with additional information about the theme. Here’s an example:

I added a demo theme of this to the Options Theme Kit if you’re interested to see exactly how it works.

Here’s a slightly simpler example:

add_action('optionsframework_after','exampletheme_options_after', 100);

function exampletheme_options_after() { ?>
    <p>Content after the options panel!</p>
<?php }

I’ve hosted most of my sites with BlueHost the last six years, but I recently migrated this one over to WP Engine. I was mainly curious to see what the impact on page speed would be. As WP Theming has grown in traffic so have load times– despite good caching, gzipped files, minified scripts and css, and sprited images.

Page Speed

The home page of the site had a page speed score of 96% before the migration and roughly 81% after. No theme code changed and the only plugin removal was W3 Total Cache. However, load times improved significantly (as measured by Google):

You’ll notice average page speed is 1.47 seconds faster, which is a significant 25% improvement. I’d venture to guess the numbers might be even more impressive for someone who had not already worked to optimize load times.
