The new display is one I like a lot. I like how you have the option of backgrounds.
But, I have many cities that I watch and I watch potential cities that I want to travel to. But I can no longer observe them.
You get a choice over languages, but Chinese cities are now displayed in English. So if you are unfamiliar with the name of the city in Chinese, you are screwed until you do!
I do believe the people who run this app should have considered that if a person sets the language isnt English, they want to display things in English.
Other than this, it is still a good app, I just have no idea what city I am looking at!
