Config option: disable generation of new layers 

The name of the config option is "auto-create-new-layers".
It is a per-view option and can be edited on the
"Application/Layer Properties" page.

With this option set to true (default), new layers
are automatically added to the layer list on

1. Paste of cells and shapes
2. Placing of instances

Manually adding new layers to the layer list is always possible.
