## 📊 Feature Comparison

### Before vs After

#### Match Display
```
BEFORE (Text Only):
┌──────────────────┐
│ #1 TM 95%        │
│ "Naar de..."     │
└──────────────────┘

AFTER (Source + Target):
┌───────────────────────────────────┐
│ #1 TM 95%                         │
│ ┌─────────────┐ ┌──────────────┐ │
│ │ "In order"  │ │ "Naar de..."│ │
│ └─────────────┘ └──────────────┘ │
└───────────────────────────────────┘
```

#### Compare Boxes
```
BEFORE (Horizontal):
[Current] [TM Src] [TM Tgt]  ← Cramped

AFTER (Vertical):
┌─────────────────┐
│ Current Source  │
├─────────────────┤ Resizable
│ TM Source       │
├─────────────────┤
│ TM Target       │
└─────────────────┘
```

## ✨ User Experience Improvements

### Workflow 1: Rapid Number-Based Entry
```
Translator sees:  #1 [95%]  #2 [87%]  #3 [75%]
Action:          Ctrl+1     Ctrl+2     Ctrl+3
Result:        Insert #1   Insert #2   Insert #3
```
⏱️ **Speed:** Fastest method, ~2-3 seconds per segment

### Workflow 2: Keyboard Navigation + Review
```
Arrow Keys → Select match with visual feedback
Horizontal splitter → Compare source differences
Vertical splitter → Resize for better text viewing
Enter → Accept and insert match
```
⏱️ **Speed:** ~5-10 seconds per segment (QA included)

### Workflow 3: Click + Navigate + Accept
```
Click match → Highlight in blue
↓ Arrow key → Preview next match
Enter → Insert and advance
```
⏱️ **Speed:** ~3-5 seconds per segment
