I just noticed that when mousing over any of the blue buttons in my cart such as 'update' cart or 'buy now' or 'basket' there is no lightening of the button colour or any indicator that the button has been clicked, particularly if a customer is lower on the page and cannot see the cart contents at the top right corner then it is easy to add too many items to the cart thinking an item was not added. Is there a way to highlight the hover (or mouse over)? Thankyou in advance.
