Rivers and Waterfalls!

Something i’d love to see in minecraft would be rivers adapted to terrain, to follow how the terrain is loaded, could also be a possibility for waterfalls as well as these rivers traverse the world. Then there would also be possibilities to add waterfall sounds, mist and looking for stuff in rivers like different types of stone, gold panning and so on. It would be a bug opportunity to add different kinds of ambiance, like with the waterfalls and with the sounds of the river flowing, maybe even by the banks of the rivers you can find exposed rock where there is a bigger chance to find different types of ores through panning, kind of how suspicious sand work. Maybe even dead tree logs could be found in the river, fjords could be added as well, deltas and more. Sound design like hearing the waterfall rushing from a far would be amazing. I hope to one day see these ideas come into minecraft, would be absolutely amazing to see <3
