The websocket connection for the exchange rate on the other hand, does not include any address, UTXO data. Simply just grabbing the US dollar exchange rate.
I see, but IMO it's better mention the live demo access several 3rd party website (bitfinex for exchange rate and google for font) for optional feature.
Thanks! I didn't even think about the font dependency in the bootstrap CSS file. Definitely don't want that. I'm going to remove that ASAP. Also I'll make a note of the use of bitfinex's websocket for exchange rate.
