DS Kanban 0.3.0 improves the board layout for supervising active tasks and nested agents.
- Clearer hierarchy between actionable task counts and informational usage metrics; a distinct New task action.
- Search, workspace, and status stay visible. Advanced filters and display preferences move into View options.
- Selecting a status focuses its column at a readable width.
- Agent hierarchies scroll inside a bounded region. Model and usage details expand per agent.
- Compact agent names, activity dots with text labels, and one whole-tree refresh control.
- Improved narrow-screen layout, keyboard focus, and explicit empty-column states.
- Removes the permanently unavailable cost tile while retaining capability information in Diagnostics.
Verified with typecheck, build, regression tests, and live Harness checks for focused status navigation, agent filtering, and narrow-screen layout. Harness theme tokens remain the source for colors and typography.
