It would be great if you were allowed to resend a previously sent campaign to individual addresses who were left off a list. I sent a campaign this morning and two people were left off the list, so I had to create a special list for just these two people, copy the previous campaign, and then choose the new "fake" list I created and send it to that. Then after it was sent, I had to remember to transfer those two contacts to the original list they needed to be on in the first place and delete the fake one. I hate that I have to duplicate a campaign every time I want to send it after the fact. I should be able to click on previous campaigns and forward it to whomever I want to without duplicating it. It's not like any of the content can be changed anyway.
