S2:User Layer

These layers are automatically attached to your style when you use the customization wizard.

When using the wizard, it will override the values of properties that are, defined and/or declared as used, in the Layout Layer. Any properties defined in the Core Layer but not declared as used in the Layout Layer will not be saved.

When not using the wizard, one can manually override values of properties or redefine functions. This second method is considered to be an advanced customization as you run the risk of losing some of the custom code if you use the wizard to make any changes.
