Affinity Publisher lets you create and manage layers using the Layers panel.
From the Layers panel, you can create layers that can be used to place objects in your design. Multiple 'stacked' layers present layer objects in a logical, ordered and managed manner.
In addition, a child layer of any currently selected layer can be created. Use child layers for more complex multi-object designs where storing related objects in child layers under the parent layer might help object management further. Also use them to restrict adjustments and effects to the child layer only, instead of an entire layer.
Layers or child layers are created above or inside the currently selected layer, respectively.
To create a new layer:The layer will be placed at the top of your layer stack.
