Invisible Stack will let you hide everything inside of it. In my workflow I often create different kinds of Stacks on a page. From time to time I add some Stacks to specific pages which do not team up nicely with existing ones. Instead of deleting those (which I surely will need again) I created Invisible Stack which just disables everything inside of it by setting its display property to "hidden". You have an option in the Stacks to enter or leave this invisible-mode.
