Cross rates

Idea from bitcointalk:

brandondayton: Don't know if this has been suggested before, but it'd be a great feature to see bitcoin value in dollars right in the client.

giszmo: Yes, this has been requested. Problems are:

• High volatility doesn't allow give a definite rate.
• External dependency

I would be fine with an extra field where I can enter any or the latest rate at the press of a button from the exchange of my choice and it turns red whenever it is off by more than x%.

jim618: Yes - I think having a 'cross-rate' as per giszmo's suggestion would help usability.

For the early adopter 'bitcoiners' I think they are happy to think in terms of bitcoins but for wider adoption being able to present the info in a fiat currency would make it easier.

A single cross-rate where you switch the presentation of all figures (like on a website when you switch from, say, US dollars to euros) would probably be the way to go. I like giszmo's suggestion of a 'rate-out-of-date' colour scheme too.
