Hey there, in one of the reviews i saw another user (@florisassies) suggesting to include a sort function.
Now i’m no coder but i asked ChatGPT and it tweaked the plugin and it works.
<?php
/**

* Author: Adapted Plugin
*/// If this file is called directly, abort
if ( ! defined( 'WPINC' ) )

// Only run plugin in the admin
if ( ! is_admin() )
return;
// Add slug column to admin posts/pages lists
function add_slug_column($columns)
$columns['slug'] = __('Slug');
return $columns;
add_filter('manage_posts_columns', 'add_slug_column');
add_filter('manage_pages_columns', 'add_slug_column');
// Populate slug column with the post slug
function display_slug_column_content($column, $post_id)
if ($column === 'slug')
$post = get_post($post_id);
echo esc_html($post->post_name); // Display the post slug
add_action('manage_posts_custom_column', 'display_slug_column_content', 10, 2);
add_action('manage_pages_custom_column', 'display_slug_column_content', 10, 2);
// Make slug column sortable
function add_slug_column_sortable($columns)
$columns['slug'] = 'slug';
return $columns;
add_filter('manage_edit-post_sortable_columns', 'add_slug_column_sortable');
add_filter('manage_edit-page_sortable_columns', 'add_slug_column_sortable');
// Modify the query to sort by slug when requested
function sort_by_slug_column($query)
if (!is_admin()
add_action('pre_get_posts', 'sort_by_slug_column');
