Free WordPress WooCommerce Cart Tab pluginFree
A big UX mistake on many eCommerce web sites is hiding access to the cart. After adding a product to the cart the visitors next logical step is to complete the purchase. Don’t frustrate your customers by making them search for the cart button!
This plugin adds a sitewide tab that displays the number of products in the cart. Clicking the tab or adding a product to the cart from a shop page will reveal the cart contents with a link to the checkout.
There are options in the Customizer to control the display.
