<p>A plugin that lets administrators easily toggle the block template lock (contentOnly) from the WordPress block editor toolbar. Take flexible control over your editing experience. (Available to administrators only. The menu is not displayed for users with editor or lower capabilities.)</p>
<h3>How to use hook</h3>
<p><strong>locky_blocky_required_capability</strong> hook allows you to change the permissions to display the lock menu provided by this plugin.</p>
<pre><code>add_filter( 'locky_blocky_required_capability', function( $default ) {
    return 'edit_others_posts'; // Editor privileges and above
});
</code></pre>
<p>It can also be made available only to specific user IDs.</p>
<pre><code>add_filter( 'locky_blocky_required_capability', function( $default ) {
    if ( get_current_user_id() === 123 ) {
        return 'read'; // Available for User ID 123 only
    }
    return 'do_not_allow'; // Otherwise, not allowed.
});
</code></pre>
<h3>Important Notice</h3>
<p>This plugin provides a feature to toggle the <code>templateLock</code> (<code>contentOnly</code>) directly from the block toolbar. If WordPress Core implements a similar feature in the future, this plugin will be deprecated and no longer maintained.</p>
<p>Thank you for your understanding.</p>

Locky Blocky


Good news: This is a God send plugin - easy, nice, ingenious, amazing, I feel embarrassed I did not think of this first.



The bad news: This feature will/should be included in the core thus making this plugin redundant.  


Good news and bad news.

Easily toggle the block template lock (contentOnly) in the WordPress block editor toolbar.
