No problem! I am glad if i can help with fresh ideas.

One more suggestion. If you implement Coin>LTC>BTC=Price thing, make this to be used only in situation if there no BTC buy offers. I think it will be ok on that way.
I will do that, the problem will be displaying that LTC price is being used because I can't (won't) display lower than 1 satoshi. If I do it will get too confusing, but I'll do my best to find a solution.
