I'm trying to figure out how to make a link that, when clicked, will empty the cart but reload or stay on the same page, updating the mini-cart. If I just do the ?cart=empty thing I get a blank page. Seems like this should be straightforward. Would be good to be able to add this anywhere (like below the minicart or in the cart itself), for instance if someone started shopping and returned later to find they wanted to start over. In my case it is possible to have literally hundreds of items in the cart, so manual emptying isn't much of an option.
