An editable Gantt chart that replaces the built-in one, with dependencies, critical path, baselines and a cross-project view.

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.

Administration → Settings → Issue tracking → Calculate the issue done ratio with is set to use the status. In that mode the value is derived from the status and a drag is refused up front, rather than accepted and then ignored on the next load.
Someone else changed that issue after your chart was drawn. The current row is sent back so the chart redraws rather than overwriting whoever saved first.
The server refused it, a cycle, or a cross-project rule. The edge is confirmed before it is drawn precisely so an invalid dependency never flashes onto the chart.
