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>.

Sticky Copy Button for Code Blocks automatically adds a floating copy button to each <code><pre><code></code> block on your website. 
It provides convenient front-end copying for developers, readers, and tutorial users.
<h3>Features</h3>

<ul>
<li>Adjustable button position (up/down and left/right)</li>
<li>Customizable labels (“Copy” / “Copied”)</li>
<li>Adjustable font size</li>
<li>Background color, text color, or transparent mode</li>

<li>Custom CSS that is safely sanitized</li>
</ul>

<h3>Detailed Settings Guide</h3>
The following explains every option in the plugin settings page.
<h3>1. Button Position</h3>
Adjust vertical position (top offset in px) 
Moves the button up or down relative to the top of the code block. 
Use positive or negative values to fine-tune vertical alignment.
Adjust horizontal position (right offset in px) 
Moves the button left or right by adjusting how far it sits from the right edge of the code block. 
Use positive or negative values to fine-tune horizontal alignment.
These values help fine-tune button alignment to avoid overlapping with theme elements.
<h3>2. Button Text and Behavior</h3>
Copy button label 
The label shown normally (default: “Copy”).
Label after copying (2 seconds) 
Once the text is copied, the button temporarily displays this label. 
Default: “Copied”.
<h3>3. Button Size</h3>
Button size (8–36 px) 
Controls the font size of the button. 
Padding is automatically adjusted based on this value.
<h3>4. Button Colors</h3>
Button text color 
Hex color of button text.
Button background color 
Hex background color. 
When copying, the plugin automatically swaps the text and background colors for visual feedback. 
However, if the background is transparent, only the text color is swapped.
Always transparent background 
If enabled: 
– The button background always becomes transparent. 
– Only text + border remain visible
<h3>5. Code Block Max Height</h3>
Code block max height (px) 
Sets a maximum height (minimum: 100px). 
Content taller than this becomes scrollable.
Enable 
Must be checked for the value to apply.
This prevents long code blocks from stretching your page layout.
<h3>6. Display Line Numbers</h3>
Display Line Numbers (Enable) 
Shows simple line numbers next to each line. 
Notes: 
– Line height is unified for consistency. 
– Theme-specific code styling is preserved. 
– Line wrapping is forcibly disabled.
This is a built-in lightweight alternative to syntax-highlighter libraries.
<h3>7. Custom Styles (CSS)</h3>
You can add any custom CSS to adjust:
<ul>
<li>Button design</li>
<li>Wrapper layout</li>
<li>Code spacing</li>
<li>Line number appearance</li>
</ul>
Usable Selectors (CSS) :
<ul>
<li>.copy-code-btn → The copy button</li>
<li>.copy-code-btn.copied → The button after Copying</li>
<li>.code-block-wrapper → Wrapper of the code block (position: relative)</li>
<li>.code-block-wrapper pre → Inner code text area (the <code><pre></code> element)</li>
<li>
.line-numbers → The container holding the line numbers
</li>
<li>
Example: 
 <code>.copy-code-btn {</code> 
     <code>font-family: "Comic Sans MS", cursive;</code> 
     <code>font-weight: 700;</code> 
     <code>border: none;</code> 
 <code>}</code> 
Note: Do not include any comments.
</li>
</ul>
