Hi I have plugins like addthis and I love using your custom post widget however things like addthis social widget will show on every content block as wordpress treats these as pages within pages.
In screen options I see "Author" and "Date"
In my regular pages I have an option to not show the addthis widget on a page with a checkbox. . . I would love to have the ability to have this in a content block so it does not repeat the widget.
