I just thought about 4 small qol updates what do you think ?
(I did my best for the images)
Mojang should add a new enchantement called "Resilience" that would keep your tools, weapons, or armor pieces at 1 durability when its about to break. When the object is at 1 durability, it becomes 3x worse (tools mine 3x slower, weapons deal 3x less damage and armor pieces protect 3x less) but it will stay at one durability until you repair it with exp or an anvil. You can only get it by trading with a villager.
This one is kinda niche but: we should be able to stop the growth of any plants the same way golden dandelions stops animals from growing up either with an item or an in-game mechanic.
Idk how yet but we could be able to extract exp from our exp level bar to either mend ourself or to give it to someone else.
The fire resistance enchant should give you the actual fire resistance effect if you have a total of at least 8 levels equipped on you (ex: fire res IV x2 or fire res IV + fire res III + fire res I). I'm not putting the limit to 12 or 16 levels because fire resistance is so trash you would need those 2 spare armor pieces to actually protect yourself.
