1. Export dialog (Ctrl+Shift+S): replaced react-hotkeys-hook handler with
a capture-phase keydown listener on window so the browser's native
"Save Page As" dialog is intercepted before it can fire.
2. Text tool: created useTextTool hook that spawns an inline textarea
overlay on canvas click, commits the text as a Konva Text object on
blur/Enter, and wired it into the useActiveToolHandlers dispatcher.
3. Undo (Ctrl+Z): removed the 500ms debounce from zundo's handleSet.
The debounce caused a race where calling undo before the timer fired
would discard the future-states stack, making undo appear to do
nothing. The equality function (keyed on _historyVersion) already
prevents intermediate states from being recorded, so the debounce
was redundant.
CRITICAL fixes:
- #14: Render source image on canvas via Konva Image + use-image hook
- #3: Wire move tool handlers (onClick, onDragEnd, onTransformEnd, draggable)
to all CanvasObjectRenderer shapes
- #4: Implement image object rendering for fill/gradient output
- #2: Show fallback text in histogram panel when no imageData provided
- #1: Forward all args in zundo handleSet debounce wrapper
HIGH fixes:
- #5: Track raw screen cursor position for brush overlay instead of
using canvas-space coordinates
- #6: Export dialog uses Konva stage.toDataURL via module-level ref
instead of DOM querySelector for correct export at any zoom/pan
- #7: Add _historyVersion increment to setAdjustment, resetAdjustments,
toggleFilter, and setFilterParam for undo tracking
- #8: Include lastAction in partialize so history labels display correctly
MEDIUM fixes:
- #10: Move useEditorShortcuts from EditorCanvas to EditorPage with
save/export callbacks
- #11: Remove _historyVersion increment from updateObject to prevent
brush strokes from flooding undo history
- #12: Apply Konva filters (Brighten, Contrast, HSL, Blur, Grayscale,
Sepia, Invert, Pixelate, Emboss, Posterize, Noise, Solarize,
Threshold, Kaleidoscope) to source image node based on store state
- Show desktop-recommended message on mobile viewports (<768px)
- Add LoadingOverlay component for canvas loading/progress states
- Add ARIA tablist/tab/aria-selected to right panel tabs
- Add "Open in Editor" link in review panel after tool processing
Implements Agent 2 deliverables for the image editor: move tool with Konva
Transformer and smart guide snapping, rectangular/elliptical marquee and
lasso selection with marching ants animation, magic wand flood fill, crop
tool with darkened overlay and rule-of-thirds grid, free transform with
numeric inputs, context menu with z-ordering and clipboard operations,
rulers with drag-to-create guides, smart alignment guides, and canvas/image
resize dialogs. Also creates the shared editor types and Zustand store with
full layer management, z-ordering, clipboard, guide, and document operations.
Implement Agent 7 features for the image editor:
- History panel with undo/redo list, action icons, and state jumping
- 51+ keyboard shortcuts via react-hotkeys-hook (tools, modifiers, clipboard)
- Export dialog with PNG/JPEG/WebP format, quality, resize, clipboard copy
- Navigator minimap with viewport rectangle, drag-to-pan, zoom slider
- Autosave/recovery system with localStorage and recovery banner
- Project save/load (.snapotter JSON format)
- Unsaved changes warning via beforeunload
- Paste from system clipboard support
Implements the layer management panel for the image editor (Features 16, 40):
- Blend mode dropdown (16 modes) and opacity slider for active layer
- Layer list with visibility/lock toggles, thumbnails, and inline rename
- Pointer-based drag reorder (not HTML5 drag API)
- Right-click context menu: Duplicate, Merge Down, Flatten All, Delete
- Layer effects section: Drop Shadow, Inner Shadow, Outer Glow, Stroke
- Each effect with enable/disable toggle and full parameter controls
- Wired into EditorRightPanel as the "Layers" tab content
Create the four-zone editor layout shell (toolbar, options bar, status
bar, right panel), welcome screen with drag-and-drop and new document
dialog, and the main editor page with clipboard paste and URL loading.
