In "Board View" there is an advanced filter called "Task Type" that I am interested in. It has three options "Planned" "Milestone" and "Backlogged"
I looked for explanations on https://help.wrike.com/hc/en-us/articles/115000193205-Board-View#sorting but didn't find any.
Is this an accurate description?
Planned = Tasks scheduled for today or a future date.
Milestone = Task set to the Milestone status
Backlogged = Task schedule in the past.
