I think they should add Speedboats (In crafting, make it like a boat but out of iron blocks / ingots maybe and possibly redstone or something. Same as a normal boat except it doesnt break if you crash it, it goes really fast and maybe a sound effect while you ride it
Also shoot splash poisons/potions from dispensers that dont just throw the potion but smash the potion the way a player does.
And chocolate cake (replace 1 of the sugar with cocoa beans) because you can easily get cocoa beans now. Maybe it should do like 1.5 hunger points per slice rather than 1.
