I know I asked for this before, but I really want it. (mumblemumblemumble, there's no search in the forums... starting over.)
We should be able to acquire ruby slippers so that we can click our heels and go home. In effect, giving us TWO teleportation spots. I really really want to be able to just go home. Home is where the heart is, but more importantly, it's where my stuff is. This became more obvious to me when my home was moved from what I thought was a relatively convenient location (hey, I picked it!), to what I think is an inconvenient location.
(Though I do think as the world gets bigger, there's going to have to be a better way to move between zones than walking. Bullet trains?)
