- What is the difference between a status of "Untouched" and "Open"?  After placing a new order sometimes they would be "Open" status, and sometimes "Untouched".

- Twice I was unable to cancel my orders.  I clicked the "X" on the Orders screen but received an Unknown Order message.  References OHXHYC-7RUCJ-FJ4ILE and OWOO7Y-O5DXH-I6TOYF.

- The "Last Updated:" time at the bottom pane would occasionally default to "4 hours ago".

- You may want to place some limits on the order entry size in BTC.  If the value is too large it overflows your internal storage, which appears to have a max of 92,233,720,368.54775807.  Similarly, USD prices with more than 5 decimal places should not be allowed.  This seems to result in an "Insufficient funds" error message at the moment when entering in very small USD prices, even if the order total is less than my balance.
