This implementation is not great at dealing with error prevention. This design does not allow the user to undo transactions, although before a transaction goes through the user must review a confirmation page. In addition, information tends to be clustered together, so mis-clicks could be an issue. To deal with this, it would be a good idea to place less information on a screen.
