## 描述

Adding Extra Tax or Amount is a lightweight WooCommerce extension that provides 
a customizable checkbox on the checkout page. When checked, it adds a pre-defined
tax or extra fee to the order total instantly via AJAX.

Key Features:
 * **Checkout Integration:** Now focused exclusively on the checkout
page for a better user experience and to prevent duplicate fees. * **Fully Customizable:**
Change colors, text, and hover effects from the admin panel. * **Calculation Types:**
Choose between a percentage (%) of the subtotal or a fixed amount. * **Real-time
Updates:** Uses WooCommerce’s `update_checkout` AJAX trigger to update totals without
page refresh. * **Open Sans Font:** Clean and modern typography. * **Enable/Disable:**
Easily toggle the plugin from the settings page.
