This request may sound odd because of how beneficial the cascading style system is for certain workflows.

That said, it would be really awesome if we had the option of right-clicking on a breakpoint and completely disconnecting it from the cascade chain.

The idea would be that when you disconnect your selection, every single change you make there, I mean everything, including deleting major aspects of the design, would only occur on that breakpoint. It would be a means of making drastic changes between separate breakpoints without the need to hide or manipulate the layouts.

It would retain the styling of what you at at the point you broke the page from the chain but from that point on, it would divert off from the rest of the layout.
