# Recent Updates - Profile Dropdown & Blank Sheet Feature

## Changes Implemented (November 29, 2025)

### 1. **Profile Dropdown with Hover Trigger**

- **Changed**: Profile dropdown now triggers on **hover** instead of click
- **Location**: `ProfileDropdown` component in `App.js`
- **How it works**:
  - Mouse enters the profile button → dropdown appears
  - Mouse leaves the dropdown area → dropdown closes
  - Click on a profile → selects it and closes dropdown

### 2. **Profile Selection Sync Across Pages**

- **Added**: Global profile synchronization using `localStorage` and custom events
- **Components Updated**:
  - `Home` component
  - `Profile` component  
  - `Planning` component
  - `ProfileDropdown` component

- **How it works**:
  1. When user selects a profile, it saves to `localStorage` with key `selected_profile_id`
  2. A custom event `profileChanged` is dispatched
  3. All components listen for this event and reload profiles
  4. Each page shows and uses the currently selected profile

- **Benefits**:
  - Profile selected on Home page reflects in Profile and Planning pages
  - Profile created in Profile page immediately appears in dropdown
  - Worship plans created use the currently selected profile
  - Selection persists across page refreshes

### 3. **Create Blank Sheet Feature**

- **Added**: New button below "Upload Lyric File" section on Home page
- **Location**: Home component in `App.js`
- **Features**:
  - Click "📄 Create Blank Sheet" button
  - Opens the same lyric modal with empty fields
  - Can manually type or paste song lyrics
  - Can add chords in the chord field
  - Has "Save to Database" and "Edit" buttons
  - Saves to song database like uploaded files

### 4. **Technical Implementation**

#### Event System for Profile Sync

```javascript
// When profile is selected:
localStorage.setItem("selected_profile_id", profile.id.toString());
window.dispatchEvent(new Event('profileChanged'));

// In components:
useEffect(() => {
  const handleProfileChange = () => {
    loadProfiles(); // Reload and sync
  };
  window.addEventListener('profileChanged', handleProfileChange);
  return () => window.removeEventListener('profileChanged', handleProfileChange);
}, []);
```

#### Hover Trigger

```javascript
<button
  onMouseEnter={() => setShowDropdown(true)}
  // Removed: onClick
>
  {selectedProfile ? selectedProfile.name : "Select Profile"} ▾
</button>
```

#### Blank Sheet Function

```javascript
function createBlankSheet() {
  setModal({
    id: null,
    title: "",
    artist: "",
    band: "",
    lyrics: "",
    chords: "",
  });
  setShowBlankSheet(false);
}
```
