Kanban Phase 6: UI Polish & Layout Fixes

Overview​

Fix UI issues in the desktop workspace kanban based on user screenshot feedback and vibe-kanban reference.

Issues Identified from Screenshot​

Issue 1: Right Detail Panel Too Narrow​

Problem: Task detail panel is truncated, content like "Research vibe-kanb..." shows incompletely Solution: Increase default panel size from 30% to 40%, and decrease minSize from 20% to 25%

Location: apps/desktop/src/pages/workspace-kanban.tsx line 992

<Panel id="task-detail" defaultSize={30} minSize={20} maxSize={50}>
// Change to:
<Panel id="task-detail" defaultSize={40} minSize={25} maxSize={60}>

Issue 2: Duplicate Column Headers​

Problem: Screenshot shows two rows of column headers - one with counts/collapse buttons (Todo 0 <<, In Progress 0 <<) and another simpler row below (Todo +, In Progress +) Root Cause: The StatisticsPanel or some collapsed state view is showing column summary, while KanbanHeader shows the actual column headers

Solution: The collapsed columns feature (Phase 3) may be conflicting. Need to review and fix the StatisticsPanel integration.

Issue 3: Redundant "Add Task" Buttons​

Problem: Multiple "Add Task" buttons appear per column Solution: Ensure only one add task button per column (in KanbanHeader)

Issue 4: Filter Bar Layout Issues​

Problem: Priority dropdown looks isolated, Stats button exists Solution: Improve toolbar layout, ensure Stats button integrates well

Issue 5: Column Collapse State Confusion​

Problem: The collapse (<<) buttons suggest collapsible columns but the UI seems inconsistent Solution: Either remove the collapse buttons or properly implement column collapse
