Some suggestions to the exchange feature
- The Total ETH field should be editable and auto compute the Amount of RKC
- The "Available Balance" amount should be clickable and auto place it in the Total ETH field.
- If you clicked the Buy/Sell Orders price, the price should be auto place in both Buy/Sell Order field.
- Add Cumulative Total in Buy/Sell Orders.
More power to this project and cheers

I highly agree here... I just had to bust out my calculator to submit my order... Was kind of a pain in the ass.... A simple click like most exchanges is needed...
