Update: If you need more functionality please see the next generation of this plugin at https://wordpress.org/extend/plugins/network-latest-posts/
Creates a widget to show a list of the most recent posts across a WordPress MU installation. It shows the most recent post from each blog. This plugin is based on the work of many authors.
This works on previous versions of WPMU, but not on previous versions of WordPress (where it doesn’t make sense).
<h3>Options</h3>
<ul>
<li>Number of posts to show – list this many posts.</li>
<li>Number of days to limit – only go back this number of days to get posts. Set to -1 for no limit (default).</li>
</ul>

Multisite Recent Posts Widget

In WordPress Multisite, new sites get a boring default template, without any custom settings or starter content.
This plugin allows you to select a specific blog on your network, a “master” one, that will be cloned every time a new blog is created.
In this way, new blogs will contain all posts, uploads, theme settings and plugin options from the master blog.
<h4>How does it work?</h4>
<ol>
<li>It uses MySQL <code>INSERT INTO ... SELECT</code> to copy every table from the “master” blog into the new one. This is fast!</li>
<li>Then it does a search and replace on the new blog’s tables, to replace the old URL with the new one. 
This is done in a way that respects serialized arrays, so your plugin’s settings will be preserved. 
(We used a heavily trimmed down version of Interconnect/IT’s <a href="https://github.com/interconnectit/Search-Replace-DB" rel="nofollow ugc">Search and Replace</a> tool for that, so go thank them for this!)</li>
<li>It proceeds to copy all files from the <code>wp-content/uploads</code> dir of your master blog into the new one’s, so that all assets will work as expected.</li>
<li>Finally it does some house clean-up, updating the new blog’s title, admin email, and user roles as needed.</li>
</ol>
Go check the screenshots, it’s really simple and does what it says. 
Give it a try!

Multisite Cloner

I was looking for this for ages! Thanks for creating this awesome plugin, exactly what I need for my current projects!

Keep up the great work!

Awesome!

This plugin has never let me down and I've used it on scores of multi-sites.   I know (at the time of writing this review) it has not been updated in a while, but it's still brilliant.  The developer has said he will update when required, so don't be put off by the last update date.  Plus he responds to support questions.  What more can you ask for.

Thank you @manuelrazzari
