MINECRAFT NEEDS THE ROCK CYCLE!

Hello! This is Mr. Wizard1234, here to talk about why minecraft needs the rock cycle. Right now, the only transformation of rocks in minecraft is lava to stone/obsidian. That needs to change. Stuff minecraft needs:

• When a piston is used to push four blocks of sand downwards with no space below them, it is turned into sandstone.
  
• When sand is placed in lava, it eventually turns into natural glass.
  
• More patches of rock naturally occur in the ground(like with gravel).
  
• There needs to be a way to crush up stone into placeable, throwable entities.
  

That's all for now, I'll be adding more to this list.
