The Freelance Admin Hider adds a new set on settings under the general settings page in the admin panel 
to allow freelancers to control which menu item the client sees 
in the admin panel when they log in.
The plugin hides specific pages and redirects the user back to the main 
admin page if he tries to visit directly one of the hidden pages.
This way the freelance has full control over themes, plugins, settings and other 
critical pages.
The plugin lets only the admin with an ID of 1 view these pages 
in a WordPress multisite installation it will be the super admin of the network.
Features of the plugin: 
Under settings > general you can select to remove all the following items from the 
menu using a check box.

WasiTools is a lightweight WordPress admin toolbox that bundles several small but essential utilities into a single, well-organized plugin. Each module can be enabled or disabled individually, so only the code you actually need is loaded.
<h4>Features</h4>
Duplicate Post — Duplicate any post or page with a single click, directly from the post list or the block editor sidebar.
Disable Comments — Globally disable comments across all post types. Removes comment-related UI from both the classic and block editor.
Maintenance Mode — Put your site in maintenance mode or show a coming soon page. Fully customizable template, logged-in admins see the site as usual.
Classic Editor — Force the classic editor for specific post types while keeping the block editor available for others.
Body Class — Add a custom CSS class to the body tag on a per-post basis, directly from the editor sidebar.
Admin Menu — Manage and reorder admin menu items to keep the backend clean and focused.
Row Actions — Customize the row action links shown in post and page list tables.
Show Customizer — Re-adds the Customize link to the Appearance menu when a block theme is active, without switching themes.
Cron Jobs — View all scheduled WordPress cron jobs, their next run time, and manage them directly from the admin.
<h4>Philosophy</h4>
Every module is optional and loaded only when enabled. WasiTools is built to stay out of your way and add zero overhead for features you don\’t use.
