Exclude layers from Layer List widget in Web AppBuilder

Idea created by bryandieter1 on Feb 18, 2015

    It would be great to have the ability to exclude layers from the layer list widget.  This is a capability in the Flex Application Builder that I used regularly.  This feature allows users to create multiple, unique layer lists within an application.
    An improvement to this functionality would be to 'include' layers in a layer list, as opposed to exclude.  By this, I mean that when configuring the widget, we can choose which layers to include in the list.  Defining excluded layers is a little bit more cumbersome.
