NEW DIMENSION

I know mojang isn't ready to add a new dimension.BUT  this new dimension is going to be accessed when you go to the end.i also wish that the end was more lush with dark matter plants and creatures so that the new dimension could more exciting to look for. i think the key to open this dimension should be that you'll have to have 3 dragon hearts to open the passage way.maybe mojang could do something on the ender dragon availability locations to easily get the hearts.at the passage way you could also put like a guardian entity.animate the portal effects.then in the other dimension there should be like a mother tree that looks like a big willow that you have to jump in the tree hallow to get teleported back to your spawn point in the overworld
