I would like to be able to nest layers so that I can have a father "DOOR" layer and sublayers "armerst" "handle" "body" and so on...
so in this example I can hide the hole door in one click, but still being able to hide only partial elements of the door (sublayers armrest, handle...)
of course is now possible to do so with objects, but objects are bad to deal with if it is a model that I have to keep on editing.
