Would be nice to have a payment method where you could pay monthly and id DIDN'T automatically do it again every month unluess you cancel. So you can pay monthly without it going on its own.

Second, being able to take on multiple missions at once would be very cool. Especially if you took 2 that go to the same place!

Yeah, i'm for the multiple missions bit, if you have enough room you can do quite a few cargo missions on the go. As for the payment method, don't be a slack arse :P If you don't want to pay for 'next month', then cancel. Easy.
