Layers in your calendar can help you to easily review your events and deadlines by scenes, even if you have a lots of scenes in CooSpace. 

Open the detailed view of the calendar and click on the "Layers" button on the right. 

If you click on the "Layers" button, a box will appear with your personal events and your scenes, where you can check or uncheck the check boxes of different layers, therefore only those will show, which you would like to see the events and deadlines of. 

By default, the events and deadlines of all the scenes (except the hidden scenes) are shown in your calendar. 

If you remove the mark from the check box then the events of those scene will not appear in the calendar. 

Personal events have an own layer. If you want to see only your personal events switch off all the other layers.
