Mike wanted to display the entries alphabetically, this would be achieved by editing the query in the shortcode. Adding
'orderby' => 'title', to the $args array should do it. The array (line 47 of br_shortcode.php) would then look like this:
$args = array( 'order' => 'ASC', 'orderby' => 'title', 'post_type' => 'blogroll', );
The query could, thus, be edited in any way you see fit - especially if you wanted to add categories as mentioned in the readme.
It’s equally flattering and gratifying when someone chooses to use something I’ve made. Thanks Mike!
