In general the popular price trackers do a lot right, red/green flashes on price data changes, mini-charts, hyperlinks to more info etc. I like http://coincap.io/

Recs:

1. Add market caps. They are useful for at a glance guaging of unfamiliar tokens.
2. It should be possible to see easily how prices are calculated. E.g. Which exchange(s) data you are using, how recent data is and and what if any formulas/weighting etc. For example it would be great if hovering the mouse over an icon displayed for example "Latest price from Bitstamp @ 21:47". Few sites do this and it bugs me.

You could also try some more novel stuff - like display latest trends in google search activity for each token, maybe even rank them accordingly and see if there are any price correlations. I'm not aware of a dashboard such as this but i'd use one if there was one. https://www.coingecko.com/en has some stats along these lines (they track dev activity and - wierdly - bing results).
