BREAKING CHANGES: - Resize handles and edit controls now render in separate overlay containers - This prevents widget overflow and scrollbar issues Major Changes: Overlay System Refactor: - Create overlay containers for resize handles and edit controls - Append handles/controls to overlays instead of widget DOM - Fix position calculations using offsetLeft/Top instead of getBoundingClientRect - Add position sync after resize/drag/reposition operations - Add cleanup methods when switching tabs Mobile Fixes: - Add pointer/touch event support for Add Widget button - Fix file upload trigger for iOS/Android compatibility - Move modals to document.body with flex centering - Fix modal button font-sizes (rem-based instead of vw) - Add mobile-responsive styling for widget dialog Bug Fixes: - Fix getActiveTabId() calls (use activeTabId property instead) - Fix file input disabled state (exclude type="file" from edit mode disable) - Fix Add Widget modal registry.getAll() destructuring (objects not arrays) - Fix edit/delete button hover (keep visible when hovering buttons) - Fix reset layout to restore deleted widgets (regenerate default layout) UI Improvements: - No more scrollbars from resize handles - Consistent button visibility in edit mode - Touch-friendly button sizes on mobile (44px min-height) - Single-column widget grid on mobile - Proper z-index stacking for overlays Files Changed: - dashboardManager.js: Overlay container management, sync methods - resizeHandler.js: Append to overlay, update positioning - editModeManager.js: Append to overlay, hover behavior, sync/cleanup - dashboardIntegration.js: Mobile touch events, file upload, modal fixes - dashboardTemplate.html: File input accessibility - style.css: Modal button font-sizes, mobile optimizations - RESIZE_HANDLES_INVESTIGATION.md: Technical investigation documentation
