Advanced Text Widget

2nd EDIT: The plugin has now been updated, so my original review stands.

1st EDIT: Even though this was a great plugin in its day, it hasn't been updated in over 2 years and was flagged as vulnerable to attack when I ran WPScan. I therefore can't recommend it for now.

Original review: Can't imagine building a WordPress site without this, it's normally the first plugin one I install. Makes adding custom content to sidebars on a per-page basis an absolute breeze. Very flexible, you can type PHP and shortcodes in the text area and it displays whatever you want. A must have for any WordPress site developer.

Essential plugin for all my sites

<p>Block Logic adds a “Block Logic” field to the “Advanced” section of the block editor (i.e Gutenberg), that lets you show or hide any block based on conditions. You can use WordPress’ <a href="https://codex.wordpress.org/Conditional_Tags" rel="nofollow ugc">Conditional Tags</a> or any general PHP code.</p>
<h4>Show or hide blocks based on</h4>
<ul>
<li>User role</li>
<li>User login status</li>
<li>Post status</li>
<li>Date and time</li>
<li>The result of a custom PHP function</li>
</ul>
<h4>Features</h4>
<ul>
<li>Show or hide any block using conditions</li>
<li>Combine conditions with “and” or “or” operators. See FAQ Writing Logic Code</li>
<li>Full flexibility: use any condition you want</li>
</ul>
<h4>Limitations</h4>
<p>Does not work with the Classic Block, Widget Block or Widget Area Block [‘core/freeform’, ‘core/legacy-widget’, ‘core/widget-area’], as the those blocks do not support block attributes. Does also not work with the HTML Block [‘core/html’] inside the Widget Screen, as this one also does not support block attributes there.</p>
<h4>Configuration</h4>
<p>Just activate the plugin. The “Block Logic” textbox will then appear in the “Advanced” section of the Gutenberg editor.</p>
