From 5c4763cb628c4d7393762b6625a0a258e8488300 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sebastian=20Kr=C3=BCger?= Date: Fri, 21 Nov 2025 17:51:32 +0100 Subject: [PATCH] feat(phase-12): add professional UI polish with status bar, navigator, and shortcuts help MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements comprehensive quality-of-life improvements for professional editing experience: **1. Status Bar Component** (`components/editor/status-bar.tsx`): - Real-time canvas dimensions display (width × height) - Live zoom percentage indicator - Dynamic cursor position tracking in canvas coordinates - FPS counter for performance monitoring - Memory usage display (when browser supports performance.memory) - Icons for each metric (Maximize2, ZoomIn, MousePointer, Activity, HardDrive) - Fixed bottom position with clean UI - Updates at 60 FPS for smooth cursor tracking - Memory updates every 2 seconds to reduce overhead **2. Mini-Map / Navigator** (`components/canvas/mini-map.tsx`): - Live thumbnail preview of entire canvas - Renders all visible layers with proper stacking order - Checkerboard background for transparency visualization - Interactive viewport indicator (blue rectangle with semi-transparent fill) - Click or drag to pan viewport to different canvas areas - Collapsible with expand/minimize toggle button - Maintains canvas aspect ratio (max 200px) - Positioned in bottom-right corner as floating overlay - Zoom percentage display at bottom - Smart scaling for optimal thumbnail size - Cursor changes to pointer/grabbing during interaction **3. Keyboard Shortcuts Help Panel** (`components/editor/shortcuts-help-panel.tsx`): - Comprehensive list of 40+ keyboard shortcuts - 7 categories: File, Edit, View, Tools, Layers, Transform, Adjustments, Help - Real-time search filtering (searches action, category, keys, description) - Beautiful kbd element styling for shortcut keys - Modal overlay with backdrop blur - Opens with `?` or `F1` keys - Closes with `Esc` key or backdrop click - Fully responsive with scrollable content - Organized sections with category headers - Shows key combinations with proper separators (+) - Optional descriptions for special shortcuts (e.g., "Hold to pan") - Footer with helpful hints **Integration Changes:** **Canvas Component** (`canvas-with-tools.tsx`): - Added `onCursorMove` prop callback for cursor position reporting - Modified `handlePointerMove` to report canvas coordinates - Created `handlePointerLeave` to clear cursor when leaving canvas - Integrated MiniMap component as overlay **Editor Layout** (`editor-layout.tsx`): - Added cursor position state management - Integrated StatusBar at bottom of layout - Added ShortcutsHelpPanel with state management - Keyboard event handlers for `?` and `F1` to open shortcuts - Cursor position passed down to CanvasWithTools and up to StatusBar **Features:** - Non-intrusive overlays that don't block canvas interaction - All components optimized for performance - Responsive design adapts to different screen sizes - Professional appearance matching app theme - Smooth animations and transitions - Real-time updates without lag **User Experience Improvements:** - Quick access to all shortcuts via `?` or `F1` - Always-visible status information in bottom bar - Easy canvas navigation with mini-map - Performance monitoring at a glance - Professional editor feel with polished UI All features tested and working smoothly with no performance impact. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- components/canvas/canvas-with-tools.tsx | 21 +- components/canvas/mini-map.tsx | 195 ++++++++++++++++++ components/editor/editor-layout.tsx | 27 ++- components/editor/shortcuts-help-panel.tsx | 220 +++++++++++++++++++++ components/editor/status-bar.tsx | 108 ++++++++++ 5 files changed, 567 insertions(+), 4 deletions(-) create mode 100644 components/canvas/mini-map.tsx create mode 100644 components/editor/shortcuts-help-panel.tsx create mode 100644 components/editor/status-bar.tsx diff --git a/components/canvas/canvas-with-tools.tsx b/components/canvas/canvas-with-tools.tsx index b632dfe..2b6b98c 100644 --- a/components/canvas/canvas-with-tools.tsx +++ b/components/canvas/canvas-with-tools.tsx @@ -18,6 +18,7 @@ import type { BaseTool } from '@/tools';
