YITH WooCommerce Sms Notifications allows you to send notification texts to admin and/or users, to communicate the changed status of an order.
The integration with SMS Notifications adds a metabox in the order detail view on the frontend, to send a message to the customer.
If you also have the YITH WooCommerce Multi Vendor plugin installed, each vendor will see this settings panel.
With YITH WooCommerce Tab Manager you can create custom tabs which you can add to your product pages.
The two plugins can be perfectly integrated allowing you to manage the tabs in frontend manager dashboard.
By installing and activating both plugins, you can create and edit your tabs directly from the frontend panel as shown below.
For further details about YITH WooCommerce Tab Manager settings, please refer to the official documentation.
