Gantt

An editable schedule where the built-in Gantt is a picture. Drag a bar to move it, drag its edge to resize, draw a dependency between two issues, and see the Critical path through the plan. Baselines record what you promised so Drift can show what actually happened. There is a per-project chart on the Gantt tab and a Gantt — all projects view across everything you can see.

Every change is an ordinary issue edit underneath — the same rules, the same history entry, the same notifications — so a drag can never be a way to move a date without leaving a trail.
