For more intricate layouts with overlapping panels & content, we offer the controls to define the order of these layers
Changing the order of layers
Select the layer that you want to bring to the front or back of the composition. Right mouse click on the selected layer.
Then proceed by selecting the Bring to front or Send to back option. This will directly change the order (Z-index) on the canvas.
Changing the order does not alter the layer structure itself within the layer panel.
