New Plugin: List Subpages Plugin for WordPress
This WordPress plugin generates a list of subpages for the page being viewed. You can use this plugin by inserting the trigger text in your page (where you want the list to appear), or by calling the function directly from your template file. One key feature of this plugin is that it can used outside the loop, which means you can display a list of subpages of the current page in your header, sidebar, or anywhere else. There are also several options available. You can change the sort method, exclude pages, adjust the page depth, show the date, and more.
This plugin was written for WordPress 2.1.3, but may work in previous versions.
