Worin unterscheidet sich eine Zeitleiste von einem Gantt-Diagramm?

Gantt is the full editable schedule for a project — you can drag tasks, manage dependencies, and work with the complete WBS. The Timeline is a read-only report view that shows only tasks marked with Show In Timeline = Yes. You cannot drag task bars to reschedule them on the Timeline; open the task and edit it in the drawer instead.
