The current version of the plugin adds the possibility to edit the display order of the posts on the main page, on the category pages and on the archive pages.
Posts can be sorted, among others by title, by type or by update date.
In addition, you can specify whether you want to ignore pinned posts and arrange them in the normal order.
You can also choose how many posts to display per page.

A really simple and lightweight plugin (73 lines of code – comments included) to sort posts on-the-fly without making a new query to the database (improves performance).
<h4>Features:</h4>
<ul>
<li>Supports all <code>order_by</code> and <code>order</code> values of the <a href="https://codex.wordpress.org/Function_Reference/query_posts#Orderby_Parameters" rel="nofollow ugc">query_posts function</a> except <code>meta_value</code> and <code>meta_value_num</code> (which require a database query).</li>
<li>Supports changing the order of all types of posts, including custom post type posts and custom post type “archive” posts.</li>
</ul>
<h4>Documentation</h4>
This plugin adds the function <code>sort_query_posts_by(string $order_by [, string $order])</code> to the global context. 
The second <code>$order</code> parameter is optional. Its default value is <code>asc</code> (ascending order).
Call this function before <a href="https://codex.wordpress.org/The_Loop" rel="nofollow ugc">the loop</a> to change how posts are ordered. 
After calling this function you can show the posts as you normally would.
You can sort posts by:
<ul>
<li>author</li>
<li>comment_count</li>
<li>date</li>
<li>id</li>
<li>menu_order</li>
<li>modified</li>
<li>parent</li>
<li>title</li>
</ul>
This is specially useful in two cases:
<ul>
<li>When you need to reorder the posts returned by the query that WordPress creates from your given URL. Custom post type “archive” posts are a great example of this case.</li>
<li>When you need the posts returned by your customized query (e.g. <code>query_posts()</code>) to be shown more than once on the same page and ordered differently.</li>
</ul>
Examples:
<pre><code><?php sort_query_posts_by('title', 'desc'); ?>
</code></pre>
The example above will sort posts by their title in descending order without making a new query to the database. 
This way sorting is performance friendly.
<pre><code><?php sort_query_posts_by('ID'); ?>
</code></pre>
The example above will sort posts by their ID in ascending order.
<pre><code><?php sort_query_posts_by('rand'); ?>
</code></pre>
The example above will sort posts randomly. When sorting randomly <code>$order</code> is ignored.
