Meet The Timeline PDApps.org Kanbaniā€™s unique Timeline view offers a different way to explore your cards by putting ones with Due Date into a time table. Columns (Y-axis) represent time. Rows (X-axis) represent lists or boards. Cells list cards due in that time frame on that list (board). With this, Timeline provides overview of dozens of cards at once, turning your Kanban board into a calendar-style planner.
