To make the Admin Panel more accessible durring gameplay as varying UIs are displayed, you can change the display layer from Hud to Overall; like this...

var GUIPanel = GUIElement.Add(new CuiPanel
{
          Image =
          {
                     Color = "1 1 1 0"
          },
          RectTransform =
          {
                     AnchorMin = config.PanelPosMin,
                     AnchorMax = config.PanelPosMax
          },
          CursorEnabled = false
}, "Overall", Name);        // <--- Line 558 was:  }, "Hud", Name);
