Icons to the left of each layer act on the layers individually. Note that layer 0 is a special layer and should not be used for general drawing purposes. In the example above the layers are named “Layer01”, “Layer02”, and “Layer03”. The lower portion of the dock shows a list of layers in the current drawing and are listed in alpha-numeric order.
