I just got back from a camp so this may be in effect, I think there should be rivers that can go from 1 block to 4 blocks wide and may have clay commonly appear around them along with greenstone (a RL rock found near rivers) this stone was used in real life due to the fact that when used in tools it lasts almost as long as iron so I think it should be like a stone pick/sword/hoe/ect. but with the durability of iron (just like in Real life) also clay should be usable for pots and may be even flower pots/potted tree
A river going to a small pond up to a large lake that can be up to 3-4 blocks deep and can be up to 5 blocks wide it can also span a long or short distance so it can be highly variable (If this is implemented I am guessing they will make it a lot less variable... so I don't expect all of this to happen)
also greenstone is a greenish stone and you can use it off of the limestone(?) in a mod I saw (I saw a greenish stone in the mod "This is minecraft" that I think was limestone) that would work...
on a side note I forgot to mention another harder to do idea, making meteor showers (1 object with iron, netherrack, or even a slime spawner inside of an obsidian shell, also may be lava and stuff like that inside.) this would be harder because blocks would have to be removed to form a crater and it would be harder to program it
also there should be waterfalls...
X Flower/sapling X
X Dirt X
X pot X
X X X
clay X Clay
X Clay X
This should be at least mostly possible
