Sum the time estimated for each step in a project, and have that total be on the front of the job tickets so operations can "at a glance" plan accordingly. It would aslo be nice if the sum of time was a viewable column you could turn on in List Manager.
We noticed this on the job bags, and it has been excellent - however I do not see this as a selectable column in "list manager" - is it named something that isn't overtly obvious?
