I always forget as well, now have a really big order and can't check the status :\ Maybe an option to use bitcoin address or email to check order instead of order number. I assume they use order number for privacy but I don't really care about that personally. Deposit address should be relativity private anyway? (not sure if they reuse any)
Good suggestion, I will look to integrate that this weekend. Also send an email or PM with the deposit address and we will provide you the order# to check the status. All deposit addresses are single use only so should be relatively private.
