Quests

I think it would be cool to add Quests.

After around 5-10 trades a villager will unlock Quests.

After that you will get a quest every time you press the quest button in the top right corner and you dont have a quest from that villager. It would have a colored star on them colored in a specific order to organize their difficulty like

Red= Hard quests. Have the best rewards. Like Get 48 Diamonds For 5 Netherite scrap

Orange= Slightly easer quests. like Get 34 Gold For 5 Diamonds

Yellow= Medium quests. Like Get 5 Iron for a stack of beef

Green=Slightly easy Quests. Like Get 50 Stone for 3 Iron.

Blue= Easy Quests. Like Get 10 Wood for 20 Stone

Purple=Easier Quests. Like Grab Some Wheat for Some Wood.

White= Easiest Quests. Like Get A stack of dirt for some wheat.

I think it would help out with not losing motivation to play. As it gives you a objective and you must fufill it.
