<p>The My Snippets plugin allows you to define custom widget content on a per-post basis from the edit post screen.</p>
<p>While the plugin is both simple and powerful, it’ll never replace such plugins as Widget Logic and Widget Context nor is that the plan. What it does is allow you to add custom widget content from the edit post screen without having to go to your Widgets screen in the admin for additional configuration.</p>
<h3>Features:</h3>
<ul>
<li>Post-by-post (or any public post type) widget content that you control.</li>
<li>Extra widget for use on your site.</li>
<li>Easy-to-use snippets settings box on the post editor.</li>
<li>Supports HTML and shortcodes.</li>
</ul>

My Snippets

Allows you to add custom widget content on a post-by-post basis from the edit post screen.

<p>The plugin restores the <code>Title</code> field (that was removed from WordPress 4.2) in the insert link popup box and adds a new <code>Add rel="nofollow" to link</code> checkbox to it.</p>
<p><strong>Gutengerg (Block Editor) Note</strong>: At the moment it’s not possible to add the functionality to Gutenberg, it’s a different system from the classic editor and it does not have a hook/filter which allows adding custom settings. As soon as it becomes possible to add the functionality to Gutenberg we will update the plugin.</p>

Title and Nofollow For Links (Classic Editor)

I just installed this on WP 4.9, and it works like a charm. I ended up adding HTML Class manipulation as well, by coping the code in the JS file that added the title field.

Works Well

works with wp 5.2.1

The plugin adds a title and a rel="nofollow" checkbox to the insert link popup box. Only for Classic Editor, NOT Block Editor.
