An item obtained from The End dragon that allows you to teleport to bed/spawn.
I find myself reluctant to travel far from my home because I like to have all my stuff stored in one place. I'd like to explore the world without having items scattered everywhere. This would make the The End more rewarding.
Name it whatever, craft it however.
PS: I'm sure this has been suggested and it must be a horrible idea to not have been implemented yet. amirite?
