# Constellation Analyzer - UX Analysis & Recommendations **Date:** 2025-10-09 **Analyst:** Claude (UX/UI Design Specialist) **Application Version:** 0.1.0 --- ## Executive Summary Constellation Analyzer has a solid foundation with multi-document workspace, customizable types, and essential graph editing features. However, there are significant opportunities to improve discoverability, workflow efficiency, and user guidance. This analysis identifies 28 actionable UX improvements across 6 categories. **Key Findings:** - Strong core functionality but lacks visual feedback and user guidance - Missing keyboard shortcuts and bulk operations slow down power users - No undo/redo creates fear of mistakes - Layout tools missing for professional-looking graphs - Limited analysis/visualization features for actual constellation analysis - Accessibility gaps that limit usability --- ## 1. CRITICAL MISSING FEATURES These features significantly impact core usability and should be prioritized. ### 1.1 Undo/Redo System **Priority:** CRITICAL **Problem:** Users fear making mistakes because there's no way to reverse actions. This creates anxiety and slows down exploration. **Why It's Needed:** - Accidental deletions are permanent - Users can't experiment freely with layout - Error recovery requires manual reconstruction - Industry-standard expectation for any editor **Implementation:** - Add history stack to workspace store (max 50 actions) - Track: node add/delete/move, edge add/delete/edit, type changes - Keyboard shortcuts: Ctrl+Z (undo), Ctrl+Y / Ctrl+Shift+Z (redo) - Show undo/redo buttons in toolbar with disabled state - Display action description on hover ("Undo: Delete Actor") **Design Pattern:** ``` [Toolbar] [Undo ↶] [Redo ↷] | [Add Actor] ... History Stack: - Move Person Actor (250, 300) → (350, 400) - Add Relation: Collaborates - Delete Actor: System XYZ ``` --- ### 1.2 Keyboard Shortcuts **Priority:** CRITICAL **Problem:** Users must reach for mouse for every action, slowing down power users significantly. **Why It's Needed:** - Professional users expect keyboard efficiency - Reduces repetitive strain from mouse use - Faster workflow for frequent operations - Current keyboard support is extremely limited **Implementation:** ``` Document Management: - Ctrl+N: New Document - Ctrl+O: Document Manager - Ctrl+S: Export Current Document - Ctrl+W: Close Current Tab - Ctrl+Tab: Next Document - Ctrl+Shift+Tab: Previous Document Graph Editing: - Delete/Backspace: Delete selected (already works) - Ctrl+A: Select All - Ctrl+D: Duplicate Selected - Escape: Deselect All / Close Panels - Ctrl+Z: Undo - Ctrl+Y: Redo Node Creation (Quick Add): - P: Add Person - O: Add Organization - S: Add System - C: Add Concept View: - F: Fit View to Content - Ctrl+0: Reset Zoom (100%) - Ctrl++: Zoom In - Ctrl+-: Zoom Out - G: Toggle Grid Selection: - Shift+Click: Multi-select - Ctrl+Click: Add/Remove from selection ``` **UI Enhancement:** - Add keyboard shortcuts to menu items (already partially done) - Add "Keyboard Shortcuts" menu item or modal (? key) - Show tooltip hints on buttons ("Add Person (P)") --- ### 1.3 Visual Feedback for Interactions **Priority:** CRITICAL **Problem:** Users don't receive clear feedback about actions, system state, or what's happening. **Why It's Needed:** - Users unsure if actions succeeded - No loading states for file operations - No success/error notifications - Confusing when nothing appears to happen **Implementation:** **Toast Notifications:** ```typescript // Add toast notification system - Success: "Document exported successfully" - Error: "Failed to import file: Invalid format" - Info: "Viewport restored to saved position" - Warning: "Unsaved changes will be lost" Position: Top-right corner Duration: 3-5 seconds Dismissible: Yes (X button) Max visible: 3 stacked ``` **Loading Indicators:** - File import/export operations - Workspace operations - Large graph rendering **Action Feedback:** - Node created: Brief highlight animation - Edge created: Pulse animation - Item deleted: Fade out animation - Item updated: Subtle flash **Visual States:** - Hover states on all interactive elements (improve existing) - Active/selected states (already exists, enhance) - Disabled states for unavailable actions - Focus indicators for keyboard navigation --- ### 1.4 Search and Filter **Priority:** HIGH **Problem:** In complex graphs with many nodes, users can't find specific actors or relations quickly. **Why It's Needed:** - Large graphs become difficult to navigate - Can't find specific nodes by name - No way to filter by type - Can't identify all instances of a relation type **Implementation:** **Search Panel (Collapsible Sidebar):** ``` ┌─────────────────────────┐ │ 🔍 Search & Filter │ ├─────────────────────────┤ │ Search: [_____________] │ │ │ │ Filter by Actor Type: │ │ ☑ Person │ │ ☑ Organization │ │ ☐ System │ │ ☑ Concept │ │ │ │ Filter by Relation: │ │ ☑ Collaborates │ │ ☐ Reports To │ │ ☑ Depends On │ │ ☑ Influences │ │ │ │ Results: 12 actors │ │ [Clear Filters] │ └─────────────────────────┘ ``` **Features:** - Real-time search as user types - Search matches: node label, description, type - Highlight matching nodes on canvas - Click result to focus/center on node - Filter visibility (dim/hide non-matching) - Keyboard shortcut: Ctrl+F to open search **Visual Feedback:** - Matching nodes: highlight with glow - Non-matching nodes: reduce opacity to 30% - Search result count indicator --- ### 1.5 Bulk Selection and Operations **Priority:** HIGH **Problem:** Users can only operate on one item at a time, making large-scale edits tedious. **Why It's Needed:** - Repositioning multiple related nodes - Deleting multiple actors at once - Changing type for multiple items - Grouping related items **Implementation:** **Selection Methods:** - Shift+Click: Add to selection - Ctrl+Click: Toggle selection - Click-drag on empty canvas: Rectangle selection box - Ctrl+A: Select all nodes **Bulk Operations:** ``` When 2+ nodes selected, show floating toolbar: ┌────────────────────────────────────┐ │ [3 selected] │ │ [Delete] [Group] [Align] [Distribute] [Change Type ▼] │ └────────────────────────────────────┘ ``` **Operations:** - Delete selected: Remove all with confirmation - Change type: Dropdown to change all to same type - Align: Left/Right/Top/Bottom/Center - Distribute: Evenly space horizontally/vertically - Group: Visual grouping indicator **Visual:** - Selected nodes: blue outline + handles - Selection box: dashed blue rectangle - Selection count badge --- ## 2. WORKFLOW IMPROVEMENTS Enhance common tasks and user efficiency. ### 2.1 Quick Add Panel with Preview **Priority:** HIGH **Problem:** Users can't see what actor types look like before adding, and the toolbar takes up significant space. **Why It's Needed:** - Visual preview helps users choose correct type - Current implementation requires trial-and-error - Toolbar could be collapsible to save space **Implementation:** **Toolbar Enhancement:** ``` [▼ Add Actor] [Relation: Collaborates ▼] [Layout ▼] [View ▼] ``` When "Add Actor" clicked, show dropdown with previews: ``` ┌──────────────────────────────┐ │ Person [●] Individual │ ← Hover shows full description │ Organization [●] Company │ │ System [●] Technical │ │ Concept [●] Abstract │ ├──────────────────────────────┤ │ + Customize Actor Types... │ └──────────────────────────────┘ ``` **Features:** - Visual color indicator - Truncated description - Hover tooltip with full details - Quick access to configuration - Click item OR drag onto canvas --- ### 2.2 Smart Connection Suggestions **Priority:** MEDIUM **Problem:** When creating relations, users might miss logical connections or create incompatible relationships. **Why It's Needed:** - Helps users discover relationship patterns - Prevents logical errors - Speeds up graph construction - Provides intelligent assistance **Implementation:** **Suggestion System:** - When hovering over node handle: Show valid targets with subtle highlight - After creating connection: "Similar actors you might want to connect:" - Based on patterns: If Person→Organization exists, suggest other Persons **Visual Feedback:** ``` User hovers on Person handle: → All Organizations slightly highlight (compatible types) → All existing Persons dim (already connected) → Show tooltip: "Drag to create Collaborates relation" ``` **Configuration:** - Optional feature (enable/disable in settings) - Type-based connection rules (configure in type settings) - Pattern learning (suggest based on existing graph) --- ### 2.3 Layout Algorithms **Priority:** HIGH **Problem:** Users must manually position every node, which is tedious and produces inconsistent results. **Why It's Needed:** - Professional-looking graphs require good layout - Manual positioning is time-consuming - Difficult to achieve balanced composition - Standard feature in graph editors **Implementation:** **Layout Menu:** ``` [Layout ▼] ├─ Force-Directed (Organic) ├─ Hierarchical (Top-Down) ├─ Hierarchical (Left-Right) ├─ Circular ├─ Grid ├─ Tree ├─ Radial └─ ─────────────── └─ Align Selected ├─ Align Left ├─ Align Right ├─ Align Top ├─ Align Bottom ├─ Align Center Horizontal └─ Align Center Vertical └─ Distribute Selected ├─ Distribute Horizontally └─ Distribute Vertically ``` **Features:** - One-click auto-layout - Preserve manual adjustments (optional) - Animate layout transitions - Undo-able layout changes - Settings per layout type (spacing, direction) **Use Cases:** - Initial graph organization - Re-organize after adding many nodes - Create presentation-ready layouts - Align nodes for clarity --- ### 2.4 Duplicate and Clone **Priority:** MEDIUM **Problem:** Creating similar actors requires re-entering all properties manually. **Why It's Needed:** - Common workflow: create similar actors - Reduces repetitive data entry - Faster graph construction - Standard editor feature **Implementation:** **Methods:** 1. Context menu: "Duplicate Actor" 2. Keyboard: Ctrl+D (when node selected) 3. Drag with Ctrl held: Clone while dragging **Behavior:** - Creates new node near original (+20px offset) - Copies all properties (label, type, description, metadata) - Appends " (Copy)" to label - Enters edit mode immediately for renaming - Does NOT duplicate relations (only node properties) **Optional Enhancement:** - "Duplicate with Relations" option - Duplicate entire subgraph (selection + relations) --- ### 2.5 Templates and Patterns **Priority:** MEDIUM **Problem:** Users recreate common graph patterns repeatedly. Current template only copies types, not graph structure. **Why It's Needed:** - Common constellation patterns (org charts, system diagrams) - Saves time on repetitive structures - Ensures consistency across documents - Onboarding for new users **Implementation:** **Template Types:** 1. **Type Templates (Current):** Actor/Relation types only 2. **Structure Templates (NEW):** Pre-built graph patterns **Structure Templates:** ``` File > New from Template ├─ Blank Document ├─ Organization Hierarchy ├─ System Dependencies ├─ Stakeholder Map ├─ Process Flow └─ Custom Templates... ``` **Template Manager:** ``` ┌─────────────────────────────────────┐ │ Template Manager │ ├─────────────────────────────────────┤ │ Available Templates: │ │ • Organization Hierarchy │ │ • System Dependencies │ │ • Custom Template 1 │ │ │ │ [Create Template from Current] │ │ [Import Template] │ │ [Export Template] │ └─────────────────────────────────────┘ ``` **Features:** - Save current graph as template - Template preview thumbnails - Share templates (export/import) - Community template library (future) --- ### 2.6 Properties Panel Improvements **Priority:** MEDIUM **Problem:** Double-clicking to edit is not discoverable, properties panel is modal and blocks view. **Why It's Needed:** - Better discoverability of editing - Non-modal editing allows viewing context - More efficient property editing - Better use of screen space **Implementation:** **Persistent Side Panel:** ``` ┌─────────────────────────┐ │ Actor Properties [X] │ ├─────────────────────────┤ │ Label: [John Doe ] │ │ │ │ Type: [Person ▼] │ │ │ │ Description: │ │ ┌─────────────────────┐ │ │ │Team lead for proj...│ │ │ │ │ │ │ └─────────────────────┘ │ │ │ │ Metadata: │ │ [+ Add Field] │ │ │ │ Connected Relations: 3 │ │ • Collaborates → Jane │ │ • Reports To → Alice │ │ • Influences → Project │ │ │ │ [Delete Actor] │ └─────────────────────────┘ ``` **Features:** - Docked to right side (resizable) - Stays open while editing graph - Shows selected item properties - Quick relation overview - Live updates as you type - Collapsible when not needed **Toggle:** - Keyboard: Ctrl+I (Inspector) - Button in toolbar - Auto-show on double-click (optional) --- ### 2.7 Rich Text in Descriptions **Priority:** LOW **Problem:** Descriptions are plain text only, limiting documentation quality. **Why It's Needed:** - Complex actors need formatted documentation - Links to external resources - Lists and structured information - Better readability **Implementation:** - Markdown editor for descriptions - Support: bold, italic, lists, links, code blocks - Live preview in properties panel - Rendered markdown in node tooltip (optional) - Keep plain text as fallback --- ## 3.
