WP Live Edit is WordPress plugin that enable the user to update the content, live, on the blog. Don’t waste time going back and forth between the admin panel and the site. Just update the content immediately while reading the blog post. The plugin is using WPs strict user control access before enabling this feature, so only the users allow to edit the blog post can do it.
This now works for both posts and pages.
