Based on development by Bill Erickson (http://www.billerickson.net/shortcode-to-display-posts/). We have added support to multisite in order to be capable of reading any other blog in the network.
The DeMomentSomTres Display Posts Shortcode was written to allow users to easily display listings of posts without knowing PHP or editing template files and extendend to take the maximum profit from a network install with multiple blogs.
<h4>Usage</h4>
Add the shortcode in a post or page, and use the arguments to query based on tag, category, post type, and many other possibilities (see the Arguments). I’ve also added some extra options to display something more than just the title: include_date, include_excerpt, and image_size.
Add the parameter blog_id to change the network instance number.
See the <a href="https://codex.wordpress.org/Class_Reference/WP_Query" rel="nofollow ugc">WordPress Codex</a> for information on using the arguments.
The parameter metaorderby allows to order based on a metafield or customfield value. The parameter metaorderbynum does the same but considering the values as numbers.
<h4>History & Raison d’être</h4>
A customer of us needed a multisite website to implement multiple languages and she was using <a href="http://demomentsomtres.com/english/wordpress-plugins/demomentsomtres-language/" rel="nofollow ugc">DeMomentSomTres Language Plugin</a>. Although they could have many blogs they didn’t want to keep 3 blogs informed. However they wanted to show the blog in all the subsites. So we build this plugin allowing to show blog content from other sites in the multisite installation.

The plugin adds a new tab in your admin bar with simple but useful indications and tools.
<ul>
<li>Displays the number of queries in your page and the amount of time to generate the page.</li>
<li>Displays the php memory usage and php memory limits (constants <code>WP_MEMORY_LIMIT</code> and <code>WP_MAX_MEMORY_LIMIT</code>).</li>
<li>displays the php version and WP version.</li>
<li>Displays <code>WP_DEBUG</code>, <code>SCRIPT_DEBUG</code>, <code>WP_DEBUG_LOG</code>, <code>WP_DEBUG_DISPLAY</code>, and error reporting values.</li>
</ul>
In your site front-end:
<ul>
<li>Lists the template and all template parts used in the current page (template parts added with <code>get_template_part()</code>). Compatible with WooCommerce’s templates.</li>
<li><code>$wp_query</code>: this will open a lightbox displaying the content of <code>$wp_query</code>. Click the lightbox title to reload the value, click outside the lightbox to close it.</li>
</ul>
In your site administration:
<ul>
<li>Admin hooks: lists some oftenly used hooks (like <code>admin_init</code>). The indicator to the right of the line tells you how many times the hook has been triggered by a callback. A “P” means the hook has a parameter: hover it for more details. Click a hook (on its text) to auto-select its code, for example: click admin_init to select <code>add_action( 'admin_init', '' );</code>.</li>
<li><code>$current_screen</code>: displays the value of 4 properties of this object: <code>id</code>, <code>base</code>, <code>parent_base</code>, <code>parent_file</code>.</li>
<li><code>$...now</code>: displays the value of the well-known variables <code>$pagenow</code>, <code>$typenow</code>, and <code>$taxnow</code>.</li>
<li>On a user profile page, <code>$userdata</code>: : this will open a lightbox displaying the user’s data.</li>
</ul>
You can decide who’s gonna use this plugin (go to your profile page for all the settings). This way, the plugin’s items won’t show up to other users (your client for example). 
Also, a new menu item <code>Code Tester</code> will appear. There you are able to do some tests with your code.

Admin Bar Tools

I'm using this wonderfull tool in all my project and ask my studients to use it when they dev for WordPress.

Make a great job

In all my dev sites

This is one of those plugins I use on every WordPress project. The UI/UX is excellent, it's always there in the admin bar, you don't need to load anything. 

It's just a pity it's not updated to the latest WordPress versions. I sure hope this is not abandoned.

Thanks for sharing your work, @greglone.

So useful. Too bad it's not updated

Adds some small development tools to the admin bar.
