Add me to the pile of fans who support these features being added to the game in due course of time, but allow me to expand on a couple for ya.
Fishing - To go with a fishing mechanic, boats of various types to float over bodies of water, plus a good reason to use boats; hostile swimming mobs such as zombie piranhas and sharks and yes, waterlogged zombies.
Tools to better harvest grass - A scythe would be perfect for something easy-ish to craft in early-ish game, and then later you can construct a weed whacker and maybe even a fully motorised lawnmower.
