Timeline Tooltips
Hover a task bar or milestone to open a tooltip. It shows:
- Task or milestone name
- Start and finish dates (collapsed to one date when they fall on the same day)
- Schedule status badge (for example, On track or At risk, Overdue)

Tooltips are read-only — they help you scan the chart without opening the task. Click the bar or milestone when you need to view or edit details in the drawer.
