As easy as it gets. Add column classes to widgets with a select box, check whether the widget is the first, and save!
I’ve built this plugin for the Genesis Framework, though it will work with any theme that uses the (old) Bootstrap column classes.
You can also add your own classes through various filters to use this plugin with your theme’s grid framework.
<h4>Compatibility (IMPORTANT!)</h4>
This plugin does NOT add CSS for these columns. It ONLY adds the column classes to your widgets. The actual CSS should be added in your theme.
<h4>Filter: `genesis_widget_column_classes`</h4>
Allows you to change the available column classes
Parameters: <code>array</code> Default column classes. 
Return: <code>array</code> Array of column classes.
<h4>Filter: `genesis_widget_column_classes_capability`</h4>
Change the capability required to modify column classes. 
Since 1.2.2
Default: <code>edit_theme_options</code> 
Parameters: <code>string</code> The default capability. 
Return: <code>string</code> The new capability.
<h4>Filter `genesis_widget_column_classes_select_multiple`</h4>
Allow multiple classes to be selected. 
Since 1.3 
Return: boolean.
You can use these filters inside your theme functions.php file or in a plugin.

As of version 0.2.2 you can select which post types you’d like to have the image column. 
It simply adds a column before the title (far left) the show’s the posts featured image if it’s supported and exists.
Want to change the default image? Simply filter you own image by using <code>featured_image_column_default_image</code> 
or filter your own CSS by using the <code>featured_image_column_css</code> filter hook.
<h4>Example actions/filters</h4>
Add support for a custom default image
<pre><code>function my_custom_featured_image_column_image( $image ) {
 if ( !has_post_thumbnail() ) {
 return trailingslashit( get_stylesheet_directory_uri() ) . 'images/featured-image.png';
 }

 return $image;
}
add_filter( 'featured_image_column_default_image', 'my_custom_featured_image_column_image' );
</code></pre>
Remove support for post types Use the <code>featured_image_column_init</code> action hook for your filter.
<pre><code>function frosty_featured_image_column_init_func() {
 add_filter( 'featured_image_column_post_types', 'frosty_featured_image_column_remove_post_types', 11 ); // Remove
}
add_action( 'featured_image_column_init', 'frosty_featured_image_column_init_func' );

function frosty_featured_image_column_remove_post_types( $post_types ) {
 foreach( $post_types as $key => $post_type ) {
 if ( 'post-type' === $post_type ) // Post type you'd like removed. Ex: 'post' or 'page'
 unset( $post_types[$key] );
 }
 return $post_types;
}
</code></pre>
