This plugin is a ‘swiss army knife’ of custom fields. It allows you to manipulate them to make it easy the testing and debugging of applications.
This plugin was built in a moment of desperation when I couldn’t access phpMyAdmin in a mu website. 
I absolutely needed to manipulate the custom fields for testing and debugging, version 1.0 was up in 4 hours. 
In the following months I realized how useful the plugin was and couldn’t work anymore without it. It had become part of my standard toolset.
Features: 
1 Read/write/delete options, user fields and post fields. 
2 Populate the field with an empty array. 
3 Insert a date string and translate it into a timestamp or vice versa to emulate specific dates. 
4 Change name to a field. 
5 Copy any field’s content to any other field (for example, option to user field) even of a different name.
You can contribute to the plugin or just study the code on the <a href="https://github.com/daprela/dapre-custom-fields-tools/" rel="nofollow ugc">Github repo</a>.

This utility plugin adds a series of css classes that allow easy addition of set padding and margin to any element.
For basic use, the classes follow the format of [margin / padding][location letter: all, top, right, bottom, left, vertical, horizontal][amount: none, small, medium, large, extra large (0.5em, 1em, 2em, 4em)]
Also in the basic classes are percentages, taking the place of the last letter in the format [p][percentage] e.g. p7-5 for 7.5% or p15 for 15%.
Examples of Basic Classes:
<ul>
<li>man > margin all none = margin: 0px;</li>
<li>prl > padding right large = padding-right: 2em;</li>
<li>mvp5 > margin vertical 5% = margin: 5% 0;</li>
</ul>
Additional utility classes – First / Last child, Child / Sub
To add selective classes for adding margin / padding to the first / last child, any child, or any sub-element of the required element, simply add ‘last-‘, ‘first-‘, ‘child-‘, or ‘sub-‘ to the beginning of the basic classes.
Examples of Child Classes
<ul>
<li>last-mhxl > last-child margin horizontal extra large = last-mhxl :last-child { margin: 0 4em; }</li>
<li>last-pbn > last-child padding bottom none = last-pbn :last-child { padding-bottom: 0; }</li>
<li>first-mtm > first-child margin top medium = first-mtm :first-child { margin-top: 2em; }</li>
<li>child-mal > child margin all large = child-mal > * { margin: 4em; }</li>
<li>sub-php5 > sub elements padding horizontal 5 percent = sub-php5 * { padding: 0 5%; }</li>
</ul>
Additional utility classes – Responsive margin / padding
You can also apply the margin / padding required to certain screen widths, ranging from xl (min: 1200px) to xs (max: 480px). To use these responsive classes, add -[screen-size] to the end of the basic classes.
Examples of Responsive Classes
<ul>
<li>mrm-lg > margin right medium, large screen = (max-width: 1199px) and (min-width: 980px) margin-right: 2em;</li>
<li>pas-xs > padding all small, xsmall screen = (max-width: 480px) padding: 0.5em;</li>
<li>mhp15-md > margin horizontal 15%, medium screen = (max-width: 979px) and (min-width: 768px) margin-left: 15%; margin-right: 15%;</li>
</ul>
