Easy NIJISANJI Store is a browser extension designed to improve the usability of the NIJISANJI Official Store. If you have encountered any of the following issues, this extension might be just what you need:

• You added items to your cart to purchase later, but when you logged out, your cart information disappeared.
• You can only bookmark voice groups and not individual voices.
• Downloading purchased voices is difficult.

With Easy NIJISANJI Store, you can enjoy two main features:

1. Virtual Cart: Access a cart linked to your browser from the extension button on the top left of your browser. This cart will be retained even if you log out of the NIJISANJI Official Store. You can add items to your actual cart from the extension's "Add to Cart" option. This is particularly useful if you want to use the virtual cart as a "Buy Later" list.

2. My Library: A library button will be added next to the cart button on the top of the NIJISANJI Official Store. Clicking on this button will display a list of all the voices you have purchased. It provides quick access to the download page, which is usually only accessible from the order details in the order history.

Additionally, this extension adds a filtering feature to the NIJISANJI Official Store's product listing page, allowing you to search by category and keyword. You can search within the "Goods" and "Digital Goods" categories found in the site header.
