Show and hide a Layer
It is possible at any time to only show the layers of your choice.
The layers visible in the project window are those ticked with the white round in the first column of the timeline, under the Eye icon. The hidden layers are those which are ticked with the gray round in the same column. The layer's name is displayed in gray as the instances on the right of the Timeline.
Click on these white and gray rounds to toggle a layer from visible state to hidden state and vice versa.
You can draw only on a displayed layer.
Whatever the displaying options are, once the icon with the eye is ticked directly, you will open this sub-menu.
The first option will allow you to display only the current layer. You can also use the shortcut [=].
By default, this option only displays the current layer. However, you can manage the layer attenuation through the menu Windows > Show > Display settings. By checking the Layer attenuation option, you can then configure a reduced attenuation with the adjacent percentage box.

The other options let you act on several layers at once.
