display list of posts/pages in admin edit post/page

Basically, I thinking how i could get a mini wp-admin/edit.php view inside the wp-admin/post.php page. does this even make sense to anyone?

Try the CMS Tree Page View plugin (my favorite) or the Easily navigate pages on dashboard plugin. Both allow you to have a list of your pages on the Dashboard.

Then you should be able to add that panel using this reference:
add_meta_box to integrate the box that appears on the Dashboard (see wp_add_dashboard_widget in functions.php of CMS Tree Page View)
