Managing a large number of layers in the Trailing and Leading layer windows is quite challenging. There doesn't appear to be an option to group layers, which makes organization difficult. I strongly believe there should be a feature that allows layers to be added to the Trailing/Leading windows on demand. Alternatively, the Trailing/Leading windows could display only the layers that are currently enabled in the map or layer widget. Without such functionality, the layer management becomes chaotic, especially when dealing with numerous layers.
