Layers

Diagram content can be split into several layers. Layers allow hiding and showing details.
Layers tab in side bar contains a bar with these buttons:
- Add Layer – adds new layer
- Delete Layer – deletes active (selected) layer
- Show/Hide Layer – shows hidden layer or hides displayed layer
- Merge All Layers – merges all layers into a single layer
- Move Up Layer – moves up selected layer
- Move Down Layer – moves down selected layer

Add elements into a layer

If you want to add elements into a layer, select a layer (click on its name in the list of layers). All elements, you add into diagram will be placed in the active (selected) layer.
