# Memory Echo - UX Improvements Backlog

**Date:** 2025-01-11
**Author:** Sally (UX Designer Agent)
**Project:** Keep - Memory Echo Feature

---

## 🎯 Problem Statement

**User:** Ramez has 22+ similar notes and needs better tools to manage semantic connections.

**Current State:**
- Temporary modal showing 2 connected notes side-by-side
- Notifications when new connections detected
- Basic feedback (thumbs up/down)
- Fusion feature exists but needs better integration

**User Pain Points:**
1. *"Once we see 2-3 identical notes, how do we put them side-by-side?"* - Better management of similar notes
2. *"Can we have a merge button?"* - Intelligent fusion of similar notes
3. *"Can we put them side-by-side on a sketch?"* - Mind-map / graph view of connections

**Constraints:**
- Must remain intuitive and not clutter the UI
- Must integrate cleanly with existing Masonry grid
- Must handle scale (potentially 22+ similar notes)
- Must not overwhelm the user

---

## 💡 UX Proposals

### 1️⃣ Better Connection Display & Management

#### **Proposal: Persistent Slide-over Panel**

**Location:** Navigation bar with badge counter

```
[Notes] [Archive] [🔗 Connexions (23)] ← Badge shows total notes with connections
```

**Interaction:**
- Click badge → Slide-over panel opens from right
- Shows hierarchical list of all connections grouped by similarity
- Click on connection → Scroll to & highlight that note in grid
- Hover over note in grid → Highlight connections in slide-over

**UI Layout:**
```
┌─────────────────────────────────────────────────────┐
│  [Notes] [Archive]  [🔗 Connexions (23)]            │
├─────────────────────────────────────────────────────┤
│  Grille Masonry existante                          │
│  ┌──────┐  ┌──────┐  ┌──────┐                      │
│  │ Note │  │ Note │  │ Note │                      │
│  │  1   │  │  2   │  │  3   │                      │
│  └──────┘  └──────┘  └──────┘                      │
│                                                     │
│  ┌─────────────────────────────────┐  ← Toggle     │
│  │ 🔗 Connexions (Slide-over)     │  (right side)  │
│  │ ├─ Note A (3 connexions)       │               │
│  │ │  ├─ Note B (85%)             │               │
│  │ │  └─ Note C (72%)             │               │
│  │ └─ Note D (12 connexions)      │               │
│  │    ├─ Note E (91%)             │               │
│  │    └─ ...                      │               │
│  └─────────────────────────────────┘               │
└─────────────────────────────────────────────────────┘
```

**Features:**
- **Filter controls:** "Show only notes with 5+ connections", "Similarity 80%+"
- **Group by similarity:** Cluster similar notes
- **Search:** Search through connections
- **Collapse/Expand:** Manage large lists
- **Quick actions:** Checkbox multiple notes → "Compare selected" / "Merge selected"

**Why It Works:**
- ✅ Non-intrusive: Doesn't hide the grid
- ✅ Overview: See all connections at once
- ✅ Navigation: Quick access to any connection
- ✅ Scalable: Handles 50+ connections

---

### 2️⃣ Intelligent Note Fusion

#### **Proposal: Grouped Actions + Smart Merge**

**A. In Slide-over Panel:**

```
┌──────────────────────────────────────┐
│ 🔗 Group of similar notes            │
│ ┌─────────────────────────────────┐  │
│ │ ☑ Note A - "Machine Learning"   │  │
│ │ ☑ Note B - "ML basics"          │  │
│ │ ☑ Note C - "Intro ML"           │  │
│ │                                  │  │
│ │ [🔀 Merge 3 notes]              │  │ ← Primary button
│ └─────────────────────────────────┘  │
└──────────────────────────────────────┘
```

**B. Existing Fusion Modal (Already Implemented!)**

Current modal features:
- Preview AI-generated fusion
- Select which notes to merge
- Custom prompt
- Options (archive originals, keep tags, etc.)

**C. New Feature: "Quick Merge"**

For very similar notes (90%+ similarity):
```
[⚡ Quick Merge] → Automatically archives originals
                 → Creates fused note
                 → Adds "Fused" badge to originals with link to new note
```

**Workflow:**
```
1. User opens slide-over
2. Sees group of 5 similar notes
3. Option A: Check all 5 → Click "Merge" → Opens custom modal
   Option B: Click "⚡ Quick Merge" → Instant merge with smart defaults
4. New note created with "Fused" badge
5. Original notes archived with link to fused note
```

**Why It Works:**
- ✅ Scale: Handle 22+ notes without selecting one-by-one
- ✅ Control: Quick merge for obvious duplicates, custom for nuanced cases
- ✅ Visual feedback: "Fused" badge traces history
- ✅ Reversible: Archive keeps originals accessible

### 3️⃣ Mind-Map / Graph View

#### **Proposal: Toggle Graph View**

**New Navigation Button:**
```
[Notes] [Archive] [🕸️ Graph] ← New view
```

**Graph View UI:**
```
┌─────────────────────────────────────────────────────┐
│  🔙 Back to Grid    🔍 Zoom    🎨 Clusters          │
├─────────────────────────────────────────────────────┤
│                                                     │
│      [Note A]────────────[Note B]                   │
│         │  \              /                         │
│      85%    72%        91%                          │
│         │      \        /                           │
│      [Note C]────[Note D]────[Note E]               │
│                                                      │
│   💡 Cluster "Machine Learning" (5 notes)          │
│         │                                            │
│      [Note F]────────[Note G]                        │
│                              │                       │
│   💡 Cluster "React" (3 notes)                    │
│                                                     │
└─────────────────────────────────────────────────────┘

Legend:
─ Thick line = 80%+ similarity (highly connected)
─ Thin line = 50-79% similarity
─ 💡 = Auto-clustered by theme (AI)
```

**Features:**
- **Drag & drop:** Reposition notes manually
- **Click note:** Opens modal with:
  - Full note content
  - Connections with percentages
  - Actions: "Merge with selected", "View in grid"
- **Auto-clusters:** AI groups similar thematically (ML, React, etc.)
- **Filters:** "Show only 70%+ connections", "Hide archived"
- **Zoom & pan:** Navigate large graphs
- **Export:** Save graph as image or JSON

**Why It Works:**
- ✅ Immediate visual: See everything at once
- ✅ Scalable: Handles 50+ connections
- ✅ Actionable: Click → Compare → Merge
- ✅ Discovery: Clusters reveal patterns
- ✅ Exploration: Serendipitous connections

**Tech Stack Recommendations:**
- **React Flow** (https://reactflow.dev/) - React-native, excellent performance
- **D3.js** (https://d3js.org/) - Powerful but steeper learning curve
- **Cytoscape.js** (https://js.cytoscape.org/) - Specialized for graphs

## 📊 Success Metrics

**User Engagement:**
- % of users opening connections panel
- Average connections viewed per session
- Graph view adoption rate

**Feature Usage:**
- Number of merges per week
- % of quick merges vs custom merges
- Most used similarity threshold

**User Satisfaction:**
- Feedback on graph view usability
- Time to merge similar notes
- Reduction in duplicate notes over time

## 🚨 Open Questions

1. **Default similarity threshold:** What should be the default? (Proposed: 70%)
2. **Max connections to display:** Should we cap the list? (Proposed: 50, with pagination)
3. **Auto-archival:** Should "Quick Merge" auto-archive or ask user? (Proposed: Auto-archive with undo)
4. **Graph layout:** Which layout should be default? (Proposed: Force-directed)
5. **Cluster naming:** AI-generated or user-editable? (Proposed: AI-generated with edit option)
