Well it seems like a lovely plugin so i installed it.
It made my page list hierarchy show. So it's easy to see how the pages relate in my website, and view/edit very easily.
My only issue is the post list option. It shows the posts alright, but they don't seem to be ordered by post date. So it's all over the place un-ordered.
Hopefully you can add in some way to display the post tree in the proper post date order. Maybe also let you toggle to show the post lists by date, or page title name ascendingly or descendingly. Very basic must have.
This feature i don't think is needed for the page tree. Only needed for post tree.
