chained minecarts

Minecarts

a good source of travel and some good storage. but why can't we connect them this idea adds that with the Minecraft chain it chould connect minecarts which is surprising they did not put it in when it came out. when a player pulls the chains in a minecart if there are six and you are going up hill you will be pulled down back to leavel land. were if you use and furnace minecart it can pull ten before that happens plus the more you add the more you can pull. this chould make mining so much more reliable to move ore back to your base or to move villagers. plus it chould make mult-player worlds move alive or market place worlds and Minecraft bedrock needs the furnace minecart.
