Hiding new icons etc.

With the launch of 13.3 (very nice indeed) this script needs a little tweaking because it does not hide the new 'Edit mode' toggle.  Can anyone rectify this?  I don't have a clue :-).

if HUD then
    html("
    <style>
    .sideeditor-buttons-left .button{display: none;
    height: 0px;}
    .popupeditor2-buttons-left .button{display: none;}
    .stringeditor .stringeditor-button2{display: none;}
    .nx-backplane .popupeditor.pane .nx-button-text.blue{display: none;}
    .tab.tab-icon{display: none;}
    .hud-menu-right{display: none;}
    .HudLeftHeader_root .nav-item.head.FastClickContainer_root{display: none;}
    .nav-item.head.HudLeftHeader_backButton.FastClickContainer_root{display: block;}    
    .HudContainer_body{display: none;}
    .hud-menu-button.menu-icon.menu-icon-trash{display: none;}
    .hud-menu-button.menu-icon.menu-icon-duplicate{display: none;}
    .hud-menu-button.menu-icon.menu-icon-add{display: none;}
    .hud-menu-button.menu-icon.menu-icon-print{display:;}
    .hud-menu-group, .hud-menu-right{display:none;}
    .hud-menu-button.i-32-24.i-white.i-setting-tool.--ul-admin-button.admin-button{display:none;}

    </style>
")
end
