Sidebar & Widget Manager v3.17 WordPress

Create custom sidebars (widget areas) and replace any existing sidebar so you can display relevant content on different pages. You can now replace an existing sidebar (widget area) with a custom sidebar for one or group of pages. The content of the new sidebar will be displayed on the exact same spot as the one you select to replace only for those pages you selected.
