jQuery-powered plugin that allows expansion/collapse of subpages within pages admin (/edit.php?post_type=page) menu.
Simple plugin that allows you to collapse subpages in the Pages admin list. Especially helpful if you have a ton of pages. It uses a cookie to save the expand/collapse status of your pages.
This is loosely based on Collapse Sub-Pages by Dan Dietz (http://wordpress.org/extend/plugins/collapse-sub-pages/), which broke with the 3.0 upgrade due to UI changes and hasn't been updated. I've had to rewrite the jQuery to make it work with 3.x versions.
Because this is a jQuery, it's possible that they could make additional changes that would break it. I'll do my best to stay on top of it, but let me know if it stops working.
