Conveyer Block

For a long time, Minecraft builds have been lacking something, movement. The conveyer belt would fix this issue by allowing you to move blocks connected to it as long as there is a Redstone signal and slime/slime alternative connecting the block to the conveyer belt. The belt will also be able to move items, BUT hoppers will not be able to grab items on top of the belt, so it's better at creating motion and moving things from place A and B. You can adjust the speed of the conveyer belt using Redstone signal strength 1-8 being different speeds forward and 9-16 being different speeds backwards. Blocks will also be immediately released from the belt if they come across a section of the belt with a block in the way. I think this would be a great addition to 1.21.
