UPGRADE AT YOUR OWN RISK: We’ve added a legacy feature to the plugin which has been tested and is working on our local WordPress install. However, every environment is different, if you run into problem please visit http://blackbirdi.com/blog for support.
When used with Custom Post Type UI plug-in (https://wordpress.org/extend/plugins/custom-post-type-ui/) and Advanced Custom Fields plug-in (https://wordpress.org/extend/plugins/advanced-custom-fields/), you can easily list all of the posts within a post-type and sort by regular or custom fields.
Updated and tested on latest version of WordPress (4.0)
Most updates are because of users responding with requests. If you feel there is something that you would like to see in the plugin visit our site and post a comment.
Enjoy!
