seriously if you could add other coins and include history you would be the mannnnnn!
So my question to the community... What coins, and what exchanges would you like to see?
im only really interested in LTC but i guess NMC could be good as it looks like gox will be adding it at some point too.
if you had to focus on one thing though, i'd say the historical data. i (and probably many others) can't use the feed because i have a laptop, so whenever i shut the lid, i get huge gaps in data!
