📝 WalkthroughWalkthroughThe Kanban board now tracks expanded group IDs, provides a group header toggle, and changes expanded columns to fill available width. The root component passes expansion state through ChangesKanban group expansion
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Resizable Kanban columns are added, but swimlane views currently do not apply the expansion behavior and the new icon-only control is not identifiable to screen readers. The change is otherwise localized and mergeable with explicit owner follow-up on these bounded usability and correctness issues. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

KanBan when sub_group_by is active, preserving the existing expansion behavior
for non-swimlane columns.

activating it will expand or collapse the group. Keep the existing

Forward the expansion props in swimlane mode.
When sub_group_by is active, KanBanSwimLanes renders SubGroupSwimlane, which calls KanBan without expandedGroupIds or handleExpandedGroups. The expansion state is ignored for swimlane columns.

Add an accessible name to the new column-size button.
The button at Line 145 contains only an icon and has no aria-label or visible text. Screen readers will announce an unnamed button. Add a state-specific label so users can identify the expand and collapse actions.
