The REST API Extender is a WordPress plugin that extends the functionality of the WordPress REST API.
It provides two main features:
<ol>
<li>Permalink Options Management 
This plugin allows you to update the permalink settings of your WordPress site via the REST API. You can change the permalink structure, category base, and tag base using a simple POST request.</li>
</ol>
To update the permalink settings, send a POST request to the following endpoint: 
/wp-json/raext/permalink-options/v1/settings
The request body should include the following parameters:
<ul>
<li><code>permalink_structure</code> (string): The new permalink structure.</li>
<li><code>category_base</code> (string, optional): The new category base.</li>
<li><code>tag_base</code> (string, optional): The new tag base.</li>
</ul>
Example request: 
POST /wp-json/raext/permalink-options/v1/settings 
Content-Type: application/json
{ 
“permalink_structure”: “/%year%/%postname%/”, 
“category_base”: “categories”, 
“tag_base”: “tags” 
}
<ol>
<li>Theme Installation and Activation 
The plugin also enables you to install and activate themes from a remote URL using the REST API. You have to provide the theme URL, stylesheet, and slug, and the plugin will handle the installation and activation process.</li>
</ol>
To install and activate a theme from a remote URL, send a POST request to the following endpoint: 
/wp-json/raext/theme-manager/v1/install
The request body should include the following parameters:
<ul>
<li><code>theme_url</code> (string): The URL of the theme ZIP file.</li>
<li><code>theme_stylesheet</code> (string): The stylesheet of the theme (e.g., <code>twentytwenty</code>).</li>
<li><code>theme_slug</code> (string): The slug of the theme (e.g., <code>twentytwenty</code>).</li>
</ul>
Example request: 
POST /wp-json/raext/theme-manager/v1/install 
Content-Type: application/json
{ 
“theme_url”: “https://example.com/themes/twentytwenty.zip”, 
“theme_stylesheet”: “twentytwenty”, 
“theme_slug”: “twentytwenty” 
}

The new accessibility javascript in the Appearance > Menus panel in WordPress 3.6 can significantly slow the page load speed when using a large number of menu items (> 50). This plugin defers the accessibility processing to eliminate the scripting bottleneck and allow the Appearance > Menus screen to run much faster and more responsively.

This solution is fairly rough. Hopefully we can develop a robust solution that can eventually become part of the core. Pull requests through GitHub are welcome.
