Currently I'm not sure what metrics AIM campaigns are sorted by but it seems completely random. It would be more helpful to be able to sort them by date/duration and even better if we could see some additional reporting from the View All Campaign screen to determine what is most effective. From the current view of the screen, it's hard for me to tell the last campaign I ran if it's not still active.
I'd love for the columns to be clickable/sortable!
