Showing slugs in Pages Edit Subpanel

I am trying to manage a number of pages that have slugs that aren’t altogether obvious from the page titles. As I make changes, it would be much easier to have the slugs visible in the Pages Edit Subpanel. I don’t know how much of what I see is related to the theme, but all I have is: Title, Author, CommentCount, Date – all with data.

Is there a plugin that will show what I want, or do I just have to tweak the admin pages in the theme? Surely other people would like to see the slug names too?

Thanks
