Sometimes you don’t want to show parent directories in permalink because they are not really necessary or because you know that in the future your child directory will change it’s parent.
For example: 
+Work in progress 
–Site 1 
–Site 2 
+Work Finished 
–Site 3
In this case Site 3 originally have been part of “Work in progress”, and on job done it has been moved under “Work Finished”.
So if you install this plugin your link will be transformed in this way:
domain.com/parent_category/child_directory/post_name => domain.com/child_directory/post_name 
domain.com/category/parent_category => domain.com/parent_category 
domain.com/category/parent_category/child_directory => domain.com/parent_category/child_directory

Remove Parents

Remove Parents is a tiny plugin which remove "category" and parent categories from permalink.

It can be quite annoying when you want to delete a post but it only has a Trash link. You then need to go into the trash to delete it for real. This plugin allows you to delete a post permanently by turning the trash links into a permanent delete link when you hold down the Esc key on your keyboard.
Maybe Perma Delete adds a convenient way to permanently delete content directly from the admin without the risk of pressing it accidentally:
<ul>
<li>Esc-hover in post tables: Hold the Esc key while hovering over the Trash action in post, page, or custom post type lists. The link will change to Delete permanently for that specific row.</li>
<li>Esc-hover on the post edit screen: On the single post edit screen, hold Esc while hovering over the Move to Trash link to turn it into Delete permanently.</li>
<li>Bulk actions: The bulk actions dropdowns always include a Delete permanently option alongside the default Trash action.</li>
</ul>

Maybe Perma Delete

Hold the Esc key to get the option to permanently delete posts, pages, and other content, instead of moving them to the trash first.
