Rope Ladders For Easier Building

Rope ladders would be a kind of mix between ladders and scaffolding. You could place them on the side of a block, and right-clicking on a rope ladder while holding a rope ladder, would extend the ladder further down.

While scaffolding is great for building tall buildings, rope ladders would specialize in building underneath what you're already building on. In addition, they would also work as a visual variant of the ladder.
