The only suggestion I can make is to make list of tokens easier to search because now it's 3 per row, and with hundreds of tokens it takes times to scroll.
How did you manage to access the exchange page? It's currently unavailable/not clickable for me. (the same with wallet, orderbook, transactions etc). Does it have some private registration for beta?
Since the view is limited, the only thing I could suggest for now is for them to add a search box on the market page.
