Any Fix for Wishlist Usability Issue?

Hi, Your Wishlist plugin works as described. However, have an input on the usability of it: the Wishlist closure is not intuitive; I mean, it is difficult to understand that one has to click the hamburger icon to close an open Wishlist popup. Typically, the model for a closure of popup is it closes when you click anywhere on the screen (outside the popup) or there is a close button (X). Is it possible to customize the plugin to close the Wishlish when a user clicks anywhere on the screen? Please clarify.
