players being able to sit + item suggestions

So, I've wanted Minecraft to add a mechanic where the player can sit, as in, right click a stair and sit as well as press a key and sit down. 

I also hope in the future, Minecraft will add Amythyst, and copper tools, just so there can be more used for items that do have much.

for the amethyst tools, I'm thinking of the tools themselves being crafted with the amethyst block, so it's a bit hard to get and the durability is better than diamond but not as good as netherrite.

as for the copper, I'm thinking it be better than gold but less than diamond.
