## 🎯 Implementation Overview

### What Was Changed

**New Functionality**:
1. **Grid Layout Algorithm**: Positions folders in square-ish grid (150px spacing)
2. **Enhanced Force Simulation**: Directory-specific physics parameters
3. **Improved Zoom-to-Fit**: Better padding and margins for folder visibility
4. **Consistent Reset**: Reset view restores compact layout

**Key Parameters**:
- **Spacing**: 150px between folder centers
- **Grid**: `cols = Math.ceil(Math.sqrt(folder_count))`
- **Repulsion**: -200 for folders (vs -400 for regular nodes)
- **Padding**: 120px (vs 100px previously)
- **Margin**: 15% (vs 10% previously)

### What Was Preserved

✅ **Backward Compatibility**: All existing functionality intact
✅ **Expand/Collapse**: Works as before
✅ **Node Interactions**: No changes to click, hover, drag
✅ **Content Pane**: Unchanged
✅ **Search/Filter**: Not affected

## 📊 Before & After

### Before Implementation

```
Problem:
- Folders scattered randomly
- Not all folders visible initially
- Required panning to see structure
- Reset view didn't help

User Experience:
- Confusing initial view
- Time wasted navigating
- Hard to understand structure
```

### After Implementation

```
Solution:
✅ Folders in neat grid (150px spacing)
✅ All folders visible initially
✅ No panning needed
✅ Reset view restores grid

User Experience:
✅ Clear initial overview
✅ Immediate understanding
✅ Efficient navigation
```

## 🎓 Technical Details

### Grid Layout Algorithm

```javascript
// Calculate grid dimensions
const folders = nodes.filter(n => n.type === 'directory');
const cols = Math.ceil(Math.sqrt(folders.length));
const spacing = 150;

// Center grid in viewport
const startX = width / 2 - (cols * spacing) / 2;
const startY = height / 2 - (Math.ceil(folders.length / cols) * spacing) / 2;

// Position each folder
folders.forEach((folder, i) => {
    const col = i % cols;
    const row = Math.floor(i / cols);
    folder.x = startX + col * spacing;
    folder.y = startY + row * spacing;
});
```

### Force Simulation Parameters

```javascript
// Link distances
if (d.type === 'dir_containment' || d.type === 'dir_hierarchy') {
    return 80; // Shorter for folder hierarchies
}

// Charge (repulsion)
if (d.type === 'directory') {
    return -200; // Less repulsion for compact layout
}

// Collision radius
if (d.type === 'directory') {
    return 25; // Larger for folder icons
}
```

### Timing Sequence

```javascript
// Initial load & reset view
renderGraph();                              // 0ms
setTimeout(() => positionFoldersCompactly(), 100);  // +100ms
setTimeout(() => zoomToFit(750), 300);              // +300ms
setTimeout(() => releasePositions(), 1000);         // +1000ms
```
