Doesn't work on Pages

If anyone has gotten the plugin to appear in the edit page area (it appears on I edit posts, just not pages), it would be great if you could share what you did to make the plugin work.

Replace index.php with this to enable it to work on pages. Basically the changes are:
– replace the check for is_single() to is_singular() in sh_featured_image (line 92)
– remove ‘$sh_post_types[‘page’]’ from the unset at line 36
