Some questions about Google Now and the new Search.

So, all Google Now does for me is show me the weather and my calendar events. A question on the latter is, why doesn't it give me the directions to the location of my event and traffic and etc?

Also, almost every day, I'll be Googling for the current time in London, isn't there for Google Now to show me a card on this, constantly updated?

And I'll also be Googling for the current currency exchange rate between Australian dollars and Sri Lankan rupees. I think I've seen a screenshot of two for currency exchange rates on Google Now. How do I get this on my phone?

Finally about Search/Now, what are the offline orders you can give? So far I know only of 'Call' someone. What else?

And a big thanks in advance.
