Far too often do I find myself having to change a component or other auto-layout layer between Hug and Fill Frame, and then double click and change its child, ad nauseum. This is very common in tables, where specific cases occur in which a cell component needs to be adjusted a certain way, and I would need to change from fill to hug, for example.
It would be an enormous time saver to be able to cascade the sizing option down to all children in a single click.
