Plugin of the Week
Every once in awhile, you stumble across a plugin, theme, or another utility that just does the trick. There's no exception with the Widget Context plugin. This plugin solves many of the sidebar woes that many have (especially coming from other CMS). Widget Context allows you to specify which pages,posts, or specific URLs a particular widget appears on. It's an absolutely brilliant plugin. You can download the Widget Context plugin here or just go to Widgets panel, Add new and search for "Widget Context".
Once you install and activate it, you'll notice your widgets have a few extra parameters. You can show or hide any widget based on a post type, specifiy a URL, or only show on pages that have a certain length of characters.
