Tasks by Planner and To Do provides collaborative, visual task management for teams. The service makes use of drag-and-drop organization of task cards that can have associated assignees, files, checklists, labels, and more. The cards are organized in "buckets," and depending on what's needed, the plan can be tailored to a wide variety of needs.
