What I am suggesting: The addition of ropes, chains, amount of stress on chains and rope to where they will snap.
What will they do or accomplish: They will provide a new gameplay to minecraft, such as; The ability to climb down ravines safely with ropes, The ability to climb up walls, or a steep mountain with a rope and hook, The ability to create winches with chains for lifting blocks like an elevator, the ability for "Tension" to be involved for more variation so stress on chains or rope is a factor and may snap. That feature will allow the creation of stronger chains, and maybe the ability to create catapults or trebuchets.
What will they do in the long run: I believe that they will essentially make the community more creative, and intuitive regarding building projects, not only that but I believe they will provide more gameplay aspects to minecraft.
