Great plugin so far and potential for further greatness

Liking this a lot so far.

Can you add a feature to filter by parent when view pages list. When I activate your plugin it stops functionality of ‘Filter by parent in admin’ plugin By James Irving-Swift, which I also use sometimes.

Also, a ‘persistent’ feature would be great too, so once you have set the filter – it remains active after you leave editing a page/post and return to the page/post list.
