Furnace minecarts, and minecart improvements. (bedrock and java suggestion)

as everyone has seen in the recent update with lead changes, it would likely be possible to also tether minecarts together in the bedrock and java game engine, and with that, the furnace minecart should be added to bedrock. furnace minecarts should have a ui where you can put fuel in it (more than just coal) and the ability to change the cart's direction with a ui or stop the cart even, if you are in a minecart next to it. i feel this suggestion would fit in with modern day minecraft, and with the devs developing industrial-like stuff such as the copper golem.
