This plugin add a News custom post type to your WordPress site. Now you can keep your press releases or time-sensitive announcements in a separate list, without having to juggle categories or tags.
The plugin adds a News tab to your admin menu, which allows you to enter news items just as you would regular posts. The archive list of your news items will appear at <code>/news</code>, and individual news items will appear at <code>/news/<permalink></code>.
Default single item and archive page templates for news items are also provided. These templates have abundant IDs and classes, so that you can style them with your own CSS. 
You may also customize them by putting copies in your theme folder, and changing the markup. When you update the plugin, you will get new features and bug fixes, while keeping any customizations you made in your copies of these templates.
A list of news items may be included in other post content with the list-news-items] shortcode. (See the FAQ for more information on using the shortcode.)
Finally, the plugin adds a Recent News Items widget, which can be placed on any sidebar available in your theme, to show a list of news items in reverse chronological order. You can set the title of this list and the number of news items to show.

Adds meta boxes to all post types and allows you to convert the post type of the current post you are editing to a different post type. This very useful when doing an import from another site into one post type that then needs to be filtered into different post types or even to fill dummy posts throughout multiple post types.
