Increased durability rather than unbreakable. Unbreakable has never been a thing for Minecraft tools and we know all other iron, gold and diamond type tools break. In regards to wood, the bows are already made of wood.. Damage values should indeed be increased slightly with each tier. Overall that is what I agree and disagree with. Does that sound better to you too?
Proper inbuilt furniture, it takes time and skill to make all of the furniture items like pianos, organs, tables, chairs, thrones, etcetera. It would save a lot of time for skilled builders if they could simply place one 'block' and be done with each piece of furniture. It would also help players who cannot build so well make better interiors and play longer so that they can get the items to make the furniture pieces (if in survival).
Properly done fishing, by adding a few low AI fish mobs in the water to imitate the fish from fishing, they can also be caught via using a fishing rod as an alternative to the usual fishing, by hitting them (in the face only) with the bobber then pulling it in.
More ideas can be added, but to be real: None of these ideas will matter to Mojang and very few to Modders. So I will now end the time-wasting I have indulged in here
