Layers
It is possible to define layers for the application. Components can be assigned to one specific layer, and from the client it is possible to choose which layers are visible. If a component belongs to a layer which isn't visible, the component will be hidden.
To create a layer select View->Layer definition. Each layer must have a unique level. After layers have been defined, views can include one or more layers. The user can select which layer is visible directly in the tool bar as well.
