I have an other request for layer editing, sometimes I get long list in the layer windows, and often I need to re-organize them and deleting the empty layers, but the layer's windows manager show the name of empty layer with the same color and is impossible figure out the empty such as possible in the Layer UI, where empty are highlighted with grey color in the label.
If is possible having a correspondence of UI in the color even in the editing of layer windows, this make more easy to remove empty layers.
