Implements intelligent auto-layout system that efficiently arranges widgets to maximize space usage while respecting panel width constraints.
**Key Features:**
- Smart packing algorithm that sorts by widget area and finds optimal positions
- Respects responsive column count (2-4 columns based on panel width)
- Prefers full-width widgets when possible to eliminate gaps
- Fallback to narrower widths for better vertical packing
- Maintains minimum widget sizes
**Implementation:**
- GridEngine.autoLayout() - Core packing algorithm with collision detection
- DashboardManager.autoLayoutWidgets() - High-level API that re-renders after layout
- Auto-Arrange button in dashboard header (uses fa-table-cells-large icon)
- Event handler wired to call autoLayoutWidgets with preferFullWidth=true
**Algorithm Strategy:**
1. Sort widgets by area (largest first) for efficient packing
2. For each widget, try full-width placement first
3. Find first available position using row-by-row scan
4. If position is too far down, try narrower widths
5. Mark cells as occupied to prevent overlaps
**Testing Notes:**
- Works with current responsive column system (2-4 columns)
- Respects minimum sizes and column constraints
- Re-renders all widgets after repositioning
- Auto-saves layout changes
Part of Epic 2: Dashboard Widget Library
- Mark Tasks 2.1-2.4 as complete (code written, needs testing)
- Document architectural change (5 modular Info Box widgets)
- Add deliverables and commit hashes
- Add 'TESTING NEEDED' to all acceptance criteria
- Defer optional widgets (2.5-2.7) to post-v2.0
- Update Epic 2 status to 'In Progress (Testing Phase)'
- Note: Integration started prematurely - need to test first
- Created LayoutPersistence class with full save/load/import/export
- Implemented debounced auto-save (500ms after changes)
- Added manual save, export (JSON download), import (file picker)
- Added reset to default with confirmation
- Comprehensive dashboard validation
- Event-driven architecture with onChange listeners
- Save status indicator with real-time updates
- Event log for all persistence operations
- Auto-load saved layout on startup
- Complete integration test with all systems
Task 1.8 complete in <15 minutes (estimated 2-3 days)
EPIC 1: DASHBOARD INFRASTRUCTURE COMPLETE! 🎉
- Add ResizeHandler class with 8 resize handles (4 corners + 4 edges)
- Implement unified mouse + touch resize events
- Add real-time dimension overlay showing current size
- Grid overlay with cell highlighting during resize
- Enforce min/max size constraints (2×2 to 12×10)
- Support resizing from all 8 directions with proper cursors
- Escape key cancels resize and restores original size
- Handle position adjustment when resizing from top/left
- Touch delay (150ms) for mobile scroll compatibility
- Create mobile-ready test harness with:
- Hover-activated resize handles with fade transitions
- Touch-optimized UI
- Real-time statistics
- Event logging
- Works on desktop and mobile
- 550 lines core code, 920 lines test suite
- Comprehensive JSDoc documentation
- Add comprehensive widget dashboard system design
- Add schema system architecture with ECS pattern
- Add detailed implementation plan with 8 epics
- Include task breakdown with checkboxes for progress tracking
- Document widget development guide
- Document formula engine and YAML schema format
- Add migration strategy and backward compatibility plan
- Estimate 12-14 weeks total development time
This branch will contain all v2.0 development work:
- Widget dashboard with drag-and-drop
- Schema system with YAML definitions
- Formula engine with @ references
- Schema-driven widgets
- AI integration updates
- Mobile responsive improvements
Each epic builds on the previous with clear dependencies.
All features designed for progressive enhancement without modes.
