New version of the plugin is released with interface improvements and comparable options to custom post types and custom taxonomies. Also, plugin is compatible with latest WP 3.1 development alpha versions. Both Pro and Lite are updated.
Interface for custom post type and custom taxonomy editor is improved and looks the same for both. Custom post type have option to deactivate post type (for testing or something like that). And custom taxonomies got special features (only in Pro version, similar to custom post types). Currently there is only one special feature: to add custom taxonomy as a column on post edit grid.
If you have any more problems, please report them in the forum or in comments.
