Hi Dave,
currently, no, the order is a bit depending on your WP version. In some older versions they are listed in the order you′ve added them, in others they are random.
You are right that it would be a great option to add some sorting. However I′m extremely busy with some paid jobs right now, that′s why the updates a pretty slow atm.
But, you can give this a try; it′s a small change in coding. Open up the code-editor under the plugins tab (admin dashboard) and select “Show Post Categories”. You′ll need to edit the file category.php on line 26 (if using standard Taxonomy).
Modify this $categories = get_the_category($PostID); and change it to $categories = wp_get_post_terms($PostID, 'category', array( 'orderby' => 'parent', 'order' => 'ASC' ) );
Save it, and give it a go. What it does, is order it by parent, in an ascending order.
Please let me know if it works for you. Then I′ll include it in the source code, and will see if I can provide an additional shortcode for sorting ascending/descending).
If you would urgently need to modify the sorting, you can use the following options:
Orderby: ‘name’, ‘slug’, ‘term_group’, ‘term_id’, ‘id’, ‘description’, ‘parent’, ‘term_order’
Order: ‘ASC’, ‘DESC’
