Epic: UX Polish & Accessibility

Epic ID: EPIC-10
Priority: Could Have
Sprint Suggestion: Sprint 5

Description

Final UX polish and usability enhancements that go beyond the basic functionality delivered in other epics. This covers cross-cutting usability concerns: comprehensive keyboard shortcuts across the entire application, advanced drag-and-drop refinements, touch optimization for mobile/tablet beyond basic responsiveness, and performance tuning to ensure smooth interactions. While each feature epic includes basic usability for its domain, this epic addresses the holistic, cross-cutting UX quality.

Requirements Coverage

• Section 3.4: Usability
  • Intuitive interface (cross-cutting polish)
  • Minimal learning curve (onboarding/guidance)
  • Drag-and-drop for Gantt chart (advanced refinements beyond EPIC-06)
  • Keyboard shortcuts for power users (comprehensive, cross-cutting)
  • Touch friendly interface on mobile devices (advanced optimization)
• Section 3.2: Technical Requirements
  • Smooth Gantt chart interactions (performance tuning)
  • Fast load times (<2s) (performance optimization)

Dependencies

• All other epics (this is a polish pass after core features are built)

Goals

• Comprehensive keyboard shortcut system across all views
• Refined drag-and-drop interactions (not just Gantt -- also for reordering, status changes)
• Touch gesture optimization for tablet and mobile
• Performance profiling and optimization for smooth interactions
• Loading state indicators and skeleton screens
• Error handling UX (user-friendly error messages, recovery actions)
• Consistent visual design and interaction patterns across all features
