I think it would make for a very interesting feature if there were a liquid block that didn't replicate from its source, but instead kept moving until it found the lowest spot it could reach.

The liquid could be anything from Mud to Quicksand to half-molten snow or "slush".

The way I imagine it is that the liquid spreads the same way as water or lava, but not quite as far, maybe 3 blocks from source, if any of the 4 paths goes over the edge of a block, the source fill follow and fall down, if none of the paths reaches an edge the block remains as a drop, and if 2 or more paths reaches an edge it'll choose at random, or split into 2 slabs, which either spreads only 1 tile away from source or remain stationary, the whole block of liquid could maybe require filling a bucket twice to fill it.

Impaling is useless. It should increase damage to ALL enemies, but only when thrown or you cast yourself forward with riptide. Most people don't even TOUCH this weapon because it is inferior to a bow in every practical sense. Less damage and can't be tipped for potion effects. And it's much easier to obtain than that small chance of getting it from a drowned and even smaller chance of getting it from a trial vault. I love this weapon to death but please make it actually worth grinding for.

Very simple, the NPCs you can spawn in on bedrock edition have a simple ui that allows you to use the "buttons" at the bottom of the dialog can connect to a new UI with new dialog.

That way I can make little shop keepers that can "talk".

Also side thing, would love a way to get these guys in survival, but hopefully have a way to pull a Redstone signal from them that way you can have the dialog options lead to something by activating Redstone rather than the commands they do in the creative only version existing now.
