Request for hamburger menu

Just a couple of items

1- I like the hamburger menu, so I would like to have you include a way to select this so that this css is used:

 /* This shows the hamburger - I wanted mobile always */
.navbar-control-offcanvas {
        display: inherit;
        opacity: 100;
        visibility: visible; 
    }
/* this makes the normal menu hidden */
.site-navigation {
        display: none;
    }
}

Also if you could remove this code as well as I don’t see that it does anything but does create issues with making the mobile menu scrollable.

#offcanvas-menu .offcanvas-wraper::-webkit-scrollbar {
    width: 0;
    height: 0;
}
