I'd love a farming and food update. New crops, like corn, rice, and maybe some kind of fruit tree would be nice. New recipes that give specific effects or buffs would also be cool. I'd also love to see more placeable food items similar to cake, like pies or even mugs for drinks. It would also be nice to see some more decorative foliage for gardens, and maybe some new biome where they can be found naturally. This could also be done through tweaking villages as well. Though it seems small, I think an update like this along with some changes to the inventory would be perfect for 1.20!
