The Ticker App?

It appears that only stocks from the USA are available on the ticker? I am from the U.K. and would love to see at least the FTSE 100? Aside from this, it would be great to get all worldwide stocks?

Same wish here from a new user. Would it be possible either to allow european tickers OR make the source code available for the stock app so don’t need to start writing my own just to get my region of stocks supported?
