Suggestion

This plugin works very well so far on my site – combined with WPC AJAX Add to Cart and WPC Fly Cart. Just a suggestion:

Right now we close the popup by clicking on the close(x) button or anywhere on the overlay background. It would be great if there’s an option to close the popup by clicking the browser’s “Back Button”. More people nowadays tend to click on the Back Button to close pretty much everything, especially on mobile screens.

Something like discussed here: https://kriesi.at/support/topic/close-popop-modal-using-back-button-without-changing-url/

and here: https://eugenedae.github.io/Magnific-Popup-History-API-Demo/

With this feature, your already good plugin will have a very strong edge compared to other quick view plugins out there.
