This widget basically lists the links to static pages and sub-pages in WordPress sidebar.
If you have quite a number of static pages/sub-pages in your blog and don't want to have all the sub-pages listed in your homepage sidebar, while still like to have those sub-pages expand in parent page and sibling pages, you will find this widget useful. The widget also comes with an option to include a link to the home page, and various other options as well. Widget control is very user friendly.
