## ✅ Implemented Features

### 1. Keyboard Shortcuts System ✓

**Files Created:**
- `app/static/keyboard-shortcuts-advanced.js` (650 lines)

**Features:**
- 40+ predefined shortcuts
- Context-aware shortcuts
- Customizable shortcuts
- Shortcuts panel (`?` to view)
- Sequential shortcuts (`g d` = go to dashboard)

**Usage:**
```javascript
// The system is auto-initialized
// Press ? to see all shortcuts
// Customize via localStorage

// Register custom shortcut
window.shortcutManager.register('Ctrl+Q', () => {
    console.log('Custom action');
}, {
    description: 'Custom action',
    category: 'Custom'
});
```

**Built-in Shortcuts:**
- `Ctrl+K` - Command palette
- `Ctrl+/` - Search
- `Ctrl+B` - Toggle sidebar
- `Ctrl+D` - Dark mode
- `g d` - Go to Dashboard
- `g p` - Go to Projects
- `g t` - Go to Tasks
- `c p` - Create Project
- `c t` - Create Task
- `t s` - Start Timer
- `t l` - Log Time
- And 30+ more!

---

### 2. Quick Actions Menu ✓

> **Web UI update:** The separate bottom-right “bolt” quick-actions FAB is no longer mounted from `base.html`. Quick actions for the web app live in the unified **Floating hub** in `app/templates/base.html` (`#fabDock`, `#unifiedActionsMenu`) and are driven by `app/static/floating-actions.js`. The file `app/static/quick-actions.js` remains in the tree for reference or tooling but is not the active entry point for the main layout.

**Files Created:**
- `app/static/quick-actions.js` (300 lines)

**Features:**
- Floating action button (bottom-right)
- 6 quick actions by default
- Animated slide-in
- Keyboard shortcut indicators
- Mobile-responsive
- Auto-hide on scroll

**Actions:**
1. Start Timer
2. Log Time
3. New Project
4. New Task
5. New Client
6. Quick Report

**Customization:**
```javascript
// Add custom action
window.quickActionsMenu.addAction({
    id: 'custom-action',
    icon: 'fas fa-star',
    label: 'Custom Action',
    color: 'bg-teal-500 hover:bg-teal-600',
    action: () => { /* your code */ },
    shortcut: 'c a'
});

// Remove action
window.quickActionsMenu.removeAction('custom-action');
```

---

### 3. Smart Notifications System ✓

**Files Created:**
- `app/static/smart-notifications.js` (600 lines)

**Features:**
- Browser notifications
- Toast notifications
- Notification center UI
- Priority system
- Rate limiting
- Grouping
- Scheduled notifications
- Recurring notifications
- Sound & vibration
- Preference management

**Smart Features:**
- Idle time detection (reminds to log time)
- Deadline checking (upcoming deadlines)
- Daily summary (6 PM notification)
- Budget alerts (auto-triggered)
- Achievement notifications

**Usage:**
```javascript
// Simple notification
window.smartNotifications.show({
    title: 'Task Complete',
    message: 'Your task has been completed',
    type: 'success',
    priority: 'normal'
});

// Scheduled notification
window.smartNotifications.schedule({
    title: 'Meeting Reminder',
    message: 'Team standup in 10 minutes'
}, 10 * 60 * 1000); // 10 minutes

// Recurring notification
window.smartNotifications.recurring({
    title: 'Hourly Reminder',
    message: 'Take a break!'
}, 60 * 60 * 1000); // Every hour

// Budget alert
window.smartNotifications.budgetAlert(project, 85);

// Achievement
window.smartNotifications.achievement({
    title: '100 Hours Logged!',
    description: 'You\'ve logged 100 hours this month'
});
```

**Notification Center:**
- Bell icon in header
- Badge shows unread count
- Sliding panel with all notifications
- Mark as read functionality
- Auto-grouping by type

---

### 4. Dashboard Widgets System ✓

**Files Created:**
- `app/static/dashboard-widgets.js` (450 lines)

**Features:**
- 8 pre-built widgets
- Drag & drop reordering
- Customizable layout
- Persistent layout storage
- Edit mode toggle
- Responsive grid

**Available Widgets:**
1. **Quick Stats** - Today's hours, week's hours
2. **Active Timer** - Current running timer
3. **Recent Projects** - Last worked projects
4. **Upcoming Deadlines** - Tasks due soon
5. **Time Chart** - 7-day visualization
6. **Productivity Score** - Current score with trend
7. **Activity Feed** - Recent activities
8. **Quick Actions** - Common action buttons

**Usage:**
Add `data-dashboard` attribute to enable:
```html
<div data-dashboard class="container"></div>
```

**Customization:**
- Click "Customize Dashboard" button
