I also like a lot the new wallet showing dollar values of GB and assets,will it be possible in future to also add Euros(and eventually other FIAT currencies)?
Multicurrency Values of GB was a good option for the future. I think that is possible, Tonych can use the Coinmarketcap API instead the Bittrex API. I hope he like your Idea...
It will be possible. Not a huge priority at the moment though.
