YITH WooCommerce Quick View (Premium Plugin):

Customers opening a quick view window are more likely to buy the product they are viewing. This is because they do not have to wait for page loading. Also, because they do not have to surf back and forth among the pages to find the products they are interested in.

Among the many products available in a shop, going back to the one you prefer often becomes an annoying activity. This is because it always takes too long to find it again. Being able to open a pop-up window where to see details concerning that product makes users’ tasks easier. An Add to cart button is available too. The possibility to see immediately product details and magnified images of them makes users feel more comfortable. The website they are browsing makes them also more willing to buy. In fact, clicks before adding the product to the cart reduce as well as server load.

This way, customers do not have to wait long before the page to be loaded. This is because it is there, left behind, ready to be displayed as soon as it is clicked upon. This is how this plugin can improve sales on your website!
