Villager voices. They are annoying to no end, and I know I could just go into the resources and move the files, but ... actually, nevermind, I'm fine with that.
I don't like the new golden apple formula, especially now that they actually have a function. I understand the nugget-based formula was too easy, but eight gold ingots for one freaking apple? Cut it to 4 or 6 and I'd be happy.
I don't like that dyed clay isn't the color it says it is. Blue clay? No man, that's mauve clay. Black clay? Nope, brown. White? Pinkish. Dyed clay would be really nice as decorating blocks if you could actually dye them the color you want.
I had thought that I wished saddles and horse armor were craftable, but I've found loads of saddles and horse armor (2 iron, 2 gold, 3 diamond) with a modicum of searching for surface dungeons and temples in my desert. They're almost too common, and I now wish they were craftable and not found in chests so commonly.
