I did an animation timeline for a sliding menu. It works fine, however,  doing a reverse easing (when the menu slides back) seems a bit slow.  I'd like to make it go faster or just change the easing to a regular Power0.ease on reverse.    $('#menu').click(function () { $(this).toggleClass('open'); if ($('#menu').hasClass('open')) { tlMenu.restart(); } else { tlMenu.reverse(); } });
