MINECART MECHANISM AND INTERACTIONS.

Hello, I believe that minecarts should have a mechanism to be coupled together. Minecraft has introduced chains so lets put it to good use. A minecart should have the ability to be couple to as many minecarts as possible that also with all the types of minecarts(hopper,chest,normal minecart). I also believe that there should be a villager interaction with minecart where they can sit in minecart,now they do,but that should be improved. This can vastly improve transportation and make the game more exciting and I hope that minecraft takes this seriously and put it in the next update. Minecraft has chains,so put it for a better use.
