If you don't use this property, you'll be dealing with a unique

layer of objects (the default one). Additional layers are handy when

you don't want a set of objects to interfere with another set with
|

regard to stacking. Two layers are completely disjoint in that

matter.

Warning: Don't change the layer of

smart objects' children. Smart objects have a layer of their own,

which should contain all their child objects.
