**File:** `AppDelegate.swift`

---

### 3. Preferences Window - Tab-Based Design ✅

**After:** Clean tab interface (General | Advanced)

**New Structure:**

- Window: 600x650 (increased from 520x580)
- Tab icons: `gearshape` and `slider.horizontal.3`

**File:** `PreferencesView.swift`

---

### 4. Feedback Form - Better Defaults & Design ✅

**Changes:**
- Opens with "Feature Request" selected (was "Bug Report")
- Left-aligned layout (was center-aligned)
- Minimal SF Symbol icons (replaced emojis)
- Segmented picker for feedback type
- Prominent "Send" button styling

**Icons:**
- Feature Request: `lightbulb`
- Bug Report: `ladybug`
- Question: `questionmark.circle`

---

## 🐛 Critical Bug Fixes

### Bug #1: Empty Window on Startup ✅

**Problem:** Blank window appeared when app launched

**Solution:**
```swift
func applicationDidFinishLaunching(_ notification: Notification) {
    NSApp.setActivationPolicy(.accessory)
    
    // Close any windows created by SwiftUI
    for window in NSApp.windows {
        window.close()
    }
    
    setupMenuBar()
}
```

**File:** `AppDelegate.swift`

---

### Bug #2: Letter "W" Conversion ✅

**Problem:** Text with 'w' didn't convert from Hebrew

**Root Cause:** Hebrew keyboard produces 3 different apostrophe characters

**Solution:** Added all apostrophe variants to mapping
```swift
"'": "w",   // Regular apostrophe (U+0027)
"'": "w",   // Right single quote (U+2019)
"׳": "w",   // Hebrew geresh (U+05F3)
```

**Also Fixed:** Letter "b" mapping (now correctly maps to נ)

**File:** `LayoutConverter.swift`

---

## 🔧 Technical Improvements

### Code Quality
- Removed unused `buildPeriodTabs()` method
- Made `showAbout()` and `showFeedback()` public for cross-window integration
- Improved enum structure with `CaseIterable` and `Identifiable` conformance
- Better window management

### Design Consistency
- All SF Symbols from same family
- Consistent padding: 12-20px
- Proper typography hierarchy
- System color usage throughout
