As a small company the option of printing or emailing statments is a very valuable tool. However, after emailing the customers who provide you with an email address it would be considerably easier if the same customers did not then appear as an option on the "to be printed" Statement list. Currently you have to rely on your memory as to whom you have emailed. So my idea would be to have a default option as to "email or print statements".
