Simple Posts Order

Doug Wollison

Order Manager allows you sort posts and terms belonging to any post type or any taxonomy, 
as well as posts tagged with a specific term.
<h4>Options</h4>
Enable order manager for all posts/terms
This will add a new page to the WordPress menu under the associated post type. 
It provides you with a straightforward drag-and-drop interface to organize your 
posts or terms. If the post type or taxonomy supports a hierarchy, it will also 
let you easily reassign items to different parents by dragging them just below 
the intended parent.
This adds a new <code>'orderby'</code> value when using <code>get_terms()</code>: <code>'menu_order'</code>.
Enable post order manager for each term
Taxonomies with this option enabled will now offer a post order interface on 
each term’s edit screen, allowing you to set a unique order for posts in that 
term.
This adds a new <code>'orderby'</code> value when using <code>get_posts()</code>: <code>'term_order'</code>.
Note: this unique order will only take effect when listing posts belonging to 
a specific term that uses this.
Override order on <code>get_posts()/get_terms()</code>
This will cause all queries for posts/terms of that type to use the custom 
order by default, rather than by date/name. In the case of a query for posts 
belonging to a term with post-sorting enabled, it will use that order by default.
