Extreme Hills Changes and Placement

With the upcoming additions of actual mountains in Minecraft, we are still left with the old extreme hills biome. It's been said that the intention is to keep the extreme hills biome in the game, and because of this I think they could use a glow up and a change in their placement.

In my opinion, the extreme hills are ugly, I've never really liked them, and it's possible there are many people who feel the same way. So what I would do is change their generation slightly to make it smoother and a little bit better looking. I'm not entirely sure about the specifics of how it should look, but all I know is they need a glow up.

The second thing I'd recommend would make the extreme hills biome generate around mountain biomes, and in chains. I think having large mountain ranges dividing up your world would be a great addition to the game, and it would make it much harder and more interesting to travel long distances.

Alongside this, I just think the snow height should be increased. If I were to give a number, maybe up to 120. This snow height should be the same for all of the new mountain biomes, and the extreme hills biome as well.
