Amplitude Design

If you get confused by which widget area a widget is attached to when browsing your site then this plugin can help. 
The plugin shows the widget area names on non-admin pages and posts. This adds the widget area title to widget $params[‘before_widget’]. This will only display for the edit_posts capabilities. You must use print $params[‘before_widget’] in your widget definitions to view the area name. 
If the widget area is empty then no widget area name is displayed.
Recently added a jQuery toggle to the admin menu bar to quickly hide/show the widget area names. See +/- swan link in admin bar.
