Just an idea for developers.
A layer that has the lamp OFF, the content is hiding. Sometimes having a complex project, I do not remember what there is in it. It can be helpful, if we select the layer, in the case is off, it turns it on temporally so that you can be inspected. Now that the 3d editor is much faster, can be a nice feature that can be turned on as optional in document properties.
