Replacing the Page Parent dropdown with check boxes in WP admin

I’ve got a lot of pages and my Page attributes – parent module is quite long, which makes choosing a parent from the drop down menu very difficult.
I’d like to replace this drop down menu with one similar to the categories check box. Also I ‘ll need to collapse the child pages under the parent in order to make that menu shorter and faster for browsing. (This plugin does something similar with the /wp-admin/edit-pages.php? PageMash) and I need a plugin witch manages the Page attributes in the same manner.

I think it would be much easier for me to browse my pages and to select a parent like that.
