Display hierarchical post types and taxonomies a single level pages at a time.
*2012-03-03: Minor bug fixes when mixed Published and Draft Pages. The bug prevented getting down to or moving up the hierarchy if the child or parent were in draft status.
*2011-08-03: Minor bug fixes to declare unset variables. Thanks to the many users of my plugin who reported these issues. Note these are Warning not errors.
Added more logic on the Taxonomy Terms management screen. Have correct the pager logic. In previous versions the pager considered all the terms within the taxonomy. Now the pager is just used for the level of terms displayed. Also, on the Add new term form the dropdown for parent is now set to the parent term being displayed.
*2011-07-01: Added support for any taxonomies which are defined as hierarchical.
