How to require time spent entry when moving a task to a different column

[James Poli]

How do I require time spent on a task to be entered when someone moves a task from "To do" or "In Progress" to "Done" or to "Backlog"?

If your workflow has a transition from status "ready for dev" back to "groomed", then yes, you can do this.  If you have a batch of them, I'd use bulk edit to do it.
