“Authors” column in WordPress’ post list

Hello @rfischmann ??

Thanks for reporting this. The plugin replaces the regular “Author” column with the “Authors” column, which is not limited to avoid line breaks when a post has multiple co-authors. To show the “Authors” column in the same with the “Author” column had, you could add the following snippet to your functions.php file:

// Adjust width of authors colum in WP Admin.
add_action('admin_head', function () {
  echo '<style>.fixed .column-coauthors { width: 15%; }</style>';
});
