It would be nice if I could type in the amount of gems I want to buy with gold and the display updates with the correct amount of gold it would cost, rather than me playing around with different numbers until I get the right amount of gems.
Having the five day high, low and average is nice, I think it would be useful to have the current rate listed somewhere there too. 
Thanks for reading!
