This plugin lets you select specific themes for selected pages and blog posts. Despite its name, it works with both pages and posts. It also supports both SEO and non-SEO permalinks.
</p>
<p>
After enabling the extra columns for pages and/or posts using this screen, you will be able to select these themes on their respective screens by clicking on each page/post\'s current theme.
</p>
<p>
<strong>Note</strong>: by default, all posts and pages are displayed using the "Default Theme."
