Move project bars directly on the Gantt chart by dragging them left or right to shift dates, or by dragging the edges to resize duration. Instead of opening an edit modal every time you need to adjust a timeline, you grab the bar and drop it where it needs to go.
The current workflow requires opening the edit modal, changing start/end dates manually, and saving. For any planning session where you're adjusting multiple projects back and forth, this is tedious. Drag and drop turns the Gantt into an interactive planning surface — the primary use case for a visual planner.
