If you are working with a large number of fields in Elliot Condon’s Advanced Custom Fields, chances are you manually wrap print_r inside of pre tags while building themes. Sometimes you just need all the fields you are working with more accessible and out of the way. You will be able to bounce back and forth between fields on your current page and the options page if available, and quickly close the menu once done.
<h4>Features</h4>
<ul>
<li>Viewer button hidden until needed in the top left corner of your theme.</li>
<li>3 different color schemes for the front end viewer.</li>
<li>Supports viewing of non Advanced Custom Fields arrays! Just use <code>acfv( $array )</code>.</li>

The Custom Field Widget displays values of custom field keys, allowing post- and page-specific meta sidebar content with limitless applications.
Custom Field Widget is for WordPress 2.6.x and features:
<ul>
<li>Multiple widget instances possible</li>
<li>Widget-specific optional title and text</li>
<li>Conditional functionality, i.e., without a matching key, the widget is not displayed</li>
<li>Practically unlimited possible uses</li>
</ul>
<h3>Use</h3>
If you are unfamiliar with custom fields, you should first read about them on the <a href="https://codex.wordpress.org/Using_Custom_Fields" title="Using Custom Fields - WordPress Codex" rel="nofollow ugc">WordPress Codex</a>.
Custom fields are added to posts and pages from the Write > Page and Write > Post menus, just below the main editor area. You may add as many custom fields to a post/page as you like.
There are two separate fields for each custom field: the key and its value. The Custom Field Widget finds a specified key and then displays its corresponding value in the sidebar. Without a matching key, nothing is displayed.
The Custom Field Widget doesn’t necessarily ‘do’ anything, but it enables an advanced (and often overlooked) feature built-in to WordPress. For example, see <a href="http://performancing.com/wordpress-tips/jazz-your-site-28-ways-use-wordpress-custom-fields" title="Jazz Up Your Site: 28 Ways To Use WordPress Custom Fields" rel="nofollow ugc">28 Ways to Use WordPress Custom Fields</a> for a small picture of possibilities.
I developed this plugin for my own use. I wanted to display a small table of contents for certain pages (which are without categories) in the sidebar dynamically. Without a widget, I would have to edit the sidebar file(s) for each theme I used.
Because each table of contents (a short <code>ol</code> of items) varied from page to page, it also had to be specific to each page. So I created a custom field key of <code>toc</code> and added the <code>ol</code> of items to its value. Enabling the plugin, I had a table of contents appear in the sidebar for each page with a custom field key of <code>toc</code>.
The uses and applications of WordPress custom fields are infinite. Just <a href="http://www.google.com/search?q=wordpress+custom+fields" title="Google Search: wordpress custom fields" rel="nofollow ugc">search for WordPress custom fields</a> for thousands of results on this subject.

The good thing about small and simple plugins, is that they are robust :)
