It will be great if you can add at the top (or bottom) prices from few other major exchanges.
Name, then signal "^" or "v" in green or red and price.
For example:
Bitfinex v 254.68 | Bitstamp ^ 245.55 |
Tool is very useful and this can be an idea for improvement.
We don't plan on doing this, but you can get quick access to all prices by hitting "M" to open the market dropdown.
