I revisit my favourite cities often, but they are rotated so I have to rerotate them
I'd love if the rotation could be saved in the permalink ( 0 - 360 ) so I could reopen them rotated.
I would love if the import of landmarks also took in other changes made such as renamed districts, rotation and warped neighbourhoods.
I often adjust a city for my liking, and then once I close the tab it's gone.
It'd be great to be able to save my changes and reopen later with a json.
