I am going to be honest with saying that it could use some color coding and navigation controls that inhibit accidental activations; time stamps to the order history; and as it's clearly a mock up currently, wallet functions (including cross-transfers, which are still not utilized in the regular wallet yet either).
A btc price ticker would remain helpful; as well as collateral tickers that outline how much volume is present and moving through the platform. I don't see any sort of price graphs or for that matter, trading tools that would allow users to formulate positions unilaterally on the exchange platform.
This development is very exciting. Given any evidence of competence or security from the development personnel involved would attract a significant level of attention from skeptical and cautious investment organizations and business groups involved in franchising. As it is, I believe that this particular version is not up to par with other, more familiar options of exchange.
