Lets you disable automatic formatting like smart quotes and automatic paragraph creation, and use raw HTML/JS/CSS code in your posts without WordPress messing it up.
Features
With this plugin, you can wrap any part of your post in [raw]…[/raw] tags to prevent WordPress from converting newlines to HTML paragraphs, replacing apostrophes with typographic quotes and so on. This is very useful if you need to add a CSS block or JavaScript to your post.
RawHTML will also add new checkboxes to the “Edit Post” screen that let you disable certain WP filters on a per-post basis. This way you can:
<ul>
<li>Disable wptexturize (the function that creates smart quotes and other typographic characters).</li>
<li>Disable automatic paragraph creation.</li>
<li>Disable image smilies. </li>
<li>Disable convert_chars (the function that converts ampersands to HTML entities and “fixes” some Unicode characters).</li>
</ul>
The free version only supports editing posts in the Text tab (called “HTML” in older WordPress versions). <a href="http://rawhtmlpro.com/?utm_source=wordpress.org&utm_medium=readme_link&utm_campaign=RawHTML%20free" rel="nofollow ugc">Get the Pro version</a> if you want to be able to switch between Text and the Visual editor without WordPress messing up your content.
Compatibility
This plugin doesn’t fully support the Gutenberg editor. As of WordPress 5.0, some Raw HTML features will only work if you use the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor</a> plugin.
Usage
To prevent a part of your post or page from being filtered by WordPress, switch to the Text/HTML editor and wrap it in <code>[raw]...[/raw]</code> or <code>...</code> tags. These two versions work exactly the same, except that the latter won’t be visible to your visitors even if you deactivate Raw HTML.
Example :
<pre><code>[raw]
This 

is 

a "test"!
[/raw]
</code></pre>
In this case, the tags will prevent WordPress from inserting paragraph breaks between “This”, “is” and “a “test””, as well as ensure that the double quotes arround “test” are not converted to typographic (curly) quotes.
To avoid problems, only edit posts that contain your custom code in Text/HTML mode. If you’d like to be able to also use the Visual editor, <a href="http://rawhtmlpro.com/?utm_source=wordpress.org&utm_medium=readme_link&utm_campaign=RawHTML%20free" rel="nofollow ugc">get the Pro version</a>. It will make the code betwen [raw] tags appear as a read-only placeholder when viewed in Visual mode, ensuring WordPress doesn’t change it.
Combining shortcodes
By default, shortcodes that are inside [raw] tags will not work. They will just show up as plain text. To enable shortcodes, add the <code>shortcodes=1</code> attribute to the tag:
<pre><code>[raw shortcodes=1]This [shortcode] will be run.[/raw]

[raw]This [shortcode] won't work.[/raw]
</code></pre>
Preserving <code>[raw]</code> code in excerpts
By default, the plugin will automatically remove any code that’s inside <code>[raw]...[/raw]</code> tags from post excerpts. You can prevent that by adding the following line to <code>wp-config.php</code>:
<pre><code>define('RAW_HTML_KEEP_RAW_IN_EXCERPTS', true);
</code></pre>
This will ensure that the plugin doesn’t strip <code>[raw]</code> blocks from automatically generated excerpts.
Notes
Some features of Raw HTML will only work for users who have the “unfiltered_html” capability. In a normal WordPress install that includes the Editor and Administrator roles. In a Multisite install, only the Super Admin has this capability by default.

Advanced Editor Tools (previously TinyMCE Advanced) introduces a “Classic Paragraph” block for the block editor (Gutenberg). 
If you are not quite ready to switch to the block editor, or have plugins that cannot be used there (yet), using the Classic Paragraph block is your best option. It lets you to continue to use the familiar TinyMCE editor for most tasks, and at the same time gives you full access to all blocks and new features in the block editor.
Version 5.5 continues to improve and enhance the new features introduced in version 5.0 of the plugin. It includes an improved “Clear Formatting” button, several advanced settings for tables, and importing and exporting of the settings to a file.
If you want to continue to use the previous (“classic”) editor in WordPress 5.0 and newer, this plugin has an option to replace the new editor with the previous one. If you prefer to have access to both editors side by side or to allow your users to switch editors, it would be better to install the <a href="https://wordpress.org/plugins/classic-editor/" rel="ugc">Classic Editor plugin</a>. Advanced Editor Tools is fully compatible with the classic editor plugin and similar plugins that restore use of the previous WordPress editor.
As always this plugin will let you add, remove and arrange the buttons that are shown on the Visual Editor toolbar in the Classic Paragraph and Classic blocks in the block editor, and in the classic editor (when enabled by a plugin). There you can configure up to four rows of buttons including Font Sizes, Font Family, text and background colors, tables, etc.
It includes 15 plugins for <a href="https://www.tiny.cloud/" rel="nofollow ugc">TinyMCE</a> that are automatically enabled or disabled depending on the buttons you have chosen. 
In addition this plugin adds options for keeping the paragraph tags in text mode and importing the CSS classes from the theme’s editor-style.css.
<h4>Some of the features added by this plugin</h4>
<ul>
<li>“Classic Paragraph” block that can be used instead of or together with the standard Paragraph block.</li>
<li>An option to set the Classic Paragraph or Classic block as the default block in the block editor.</li>
<li>Supports converting of most default blocks to classic paragraphs, and from classic paragraphs back to the default blocks.</li>
<li>Support for creating and editing tables in the Classic blocks and the classic editor.</li>
<li>More options when inserting lists in the Classic blocks and the classic editor.</li>
<li>Search and Replace in the Classic blocks and the classic editor.</li>
<li>Ability to set Font Family and Font Sizes in the Classic blocks and the classic editor.</li>
<li>And many others.</li>
</ul>
<h4>Privacy</h4>
Advanced Editor Tools does not collect or store any user related data. It does not set cookies, and it does not connect to any third-party websites. It only uses functionality that is available in <a href="https://wordpress.org/" rel="ugc">WordPress</a>, and in the <a href="https://tinymce.com/" rel="nofollow ugc">TinyMCE editor</a>.
In that terms Advanced Editor Tools does not affect your website’s user privacy in any way.

This plugin is very helpful to me. Please update more feature can add custom shortcode.
Thank you very much. 

This plugin is very helpful to me.


Hey! So I only see one plugin here - Advanced Editor Tools (formerly TinyMCE Advanced). It's pretty solid if you're not ready to fully embrace Gutenberg yet. The "Classic Paragraph" block is clever - lets you use the old familiar editor within the new one. Great for folks transitioning or with older plugins that don't play nice with blocks. The table tools and formatting options are handy too. Worth a try if you miss the classic editor!
