By default, Clubhouse has three workflow states for Epics: To Do, In Progress, and Done. When you create a new Epic, its state defaults to "To Do."
The state of an Epic helps communicate the status of the overall work, and associated Stories captured in that Epic. Epics in a To Do state are represented by a white flag icon, In Progress Epics by a blue flag icon, and Done Epics are represented with a checkered flag icon.
On the Milestones page, Epic states can be helpful when scanning unstarted, in progress, or completed work across larger initiatives.
