I wish there was a way to turn off the shifting dates feature when something is scheduled during a person's time off. It is helpful is the schedule can accommodate the dates being pushed, but many of our projects (the majority in fact) are on incredibly tight deadlines so the shifting schedules feature creates a lot more problems (and work) than it solves.
If we could turn it off when needed, or even per project, that would be helpful. We adjust resources for when someone is out of the office as it comes up day by day because our schedules and deadlines shift so much as is (changes in scope, extra rounds of revisions, clients late on approval, etc.) so the automated shifts from Workfront are hard to keep track of and causes a lot more stress.
