Display full content

Hi,

thanks for this helpful plugin.

I’m trying to display the full content of each post, but don’t find the issue.
I’m looking for using that way :

add_filter( 'sya_the_title', 'my_sya_filter_title', 10, 2 );

function my_sya_filter_title( $title, $id ) {
    return $id . ' - ' . $title;
}

but I don’t know how to do it.
