This is a really tiny fix but would it be possible to make the plugin add a class to the div containing the related posts?
So basically in bawmrp.php, where it says:
$head = '<div><h3>'.$head_title.'</h3>
It could say, for example:
$head = '<div class="related_posts"><h3>'.$head_title.'</h3>
That would make it much easier to target and style/position the div containing the posts. (At the moment I am using jquery to target the div and add the class.)
