When you're in the normal posts list of the Admin, there's both a Categories and Tags column, which lists the posts' Categories and Tags. You can quickly view all posts in a single Cat/Tag by clicking it under the appropriate column.
However, on my Custom Post Type I created using this excellent plugin, in the equivalent list view, it doesn't show the Custom Taxonomies I have linked to it. That means there's no way to sort by the Custom Taxonomies via the admin (at least that I can see). It would sure make managing my custom posts a lot easier if it worked the same as normal posts. Is it possible to have Custom Taxonomies listed there in the same way? If so, how?
