# Additional UI Fixes Applied

All new feedback items have been addressed to match Paprwork v1 exactly:

## ✅ 1. Keyboard Shortcuts for Tabs

Implemented full keyboard navigation:

### macOS/Windows Shortcuts:
- **⌘/Ctrl+T**: New tab (creates new chat)
- **⌘/Ctrl+W**: Close current tab
- **⌘/Ctrl+Tab** or **⌘/Ctrl+]**: Next tab (wraps to first)
- **⌘/Ctrl+Shift+Tab** or **⌘/Ctrl+[**: Previous tab (wraps to last)
- **⌘/Ctrl+1-9**: Switch to tab by index

All shortcuts implemented in `TabBar.tsx` with proper modifier key detection (Meta for Mac, Ctrl for Windows/Linux).

## ✅ 2. Message Input Layout - Exact v1 Design

Fixed to match v1's structure:

### Layout Structure:
```
chat-input-wrapper (24px border-radius)
├── input-context-section (top - shown on focus)
│   └── add-context-pill (dashed border)
├── input-row (middle)
│   └── textarea (no scrollbar)
└── input-footer (bottom - shown on focus)
    ├── model-controls (left)
    │   ├── model-selector-pill ("Claude 3.5 Sonnet" + chevron)
    │   └── chat-history-btn (clock icon)
    └── send-button (right)
```

### Key Changes:
- **Context**: Now at TOP, inside wrapper (not outside)
- **Model & History**: Now at BOTTOM in footer
- **Scrollbar**: Completely hidden (`scrollbar-width: none`, `::-webkit-scrollbar { display: none }`)
- **Wrapper**: All controls inside the 24px rounded wrapper with border
- **Controls visibility**: Only show on focus

### Styling:
- Add context: Dashed border, 20px radius, 6px 10px padding
- Model selector: 11px font, 12px radius, 4px 8px padding
- History button: 20×20px icon button
- Send button: 32×32px circle in footer (not absolute)

## ✅ 3. Welcome Message - v1 Design

Updated to match v1 exactly:

### Content:
- **Title**: "Hey, I'm Pen! Your personal agent" (32px, weight 600)
- **Subtitle**: "What would you like help with today?" (16px, text-secondary, 40px bottom margin)

### Example Cards (2×2 Grid):
1. **Build a productivity app** (apps grid icon)
2. **Write a blog post about AI** (document icon)
3. **Find files on my computer** (inbox icon)
4. **Research a topic online** (globe icon)

### Card Styling:
- Padding: `12px 14px`
- Min-height: `48px`
- Border-radius: `8px`
- Background: `var(--card-background)` (#f5f5f7)
- Hover: `var(--card-background-hover)` (#ebebed)
- Icon: `18×18px`, color `var(--card-icon-color)` (#8E8E93)
- Text: `13px`, `line-height: 1.4`, `letter-spacing: -0.01em`

### Colors Added to CSS:
```css
--card-background: #f5f5f7;
--card-background-hover: #ebebed;
--card-background-active: #e5e5e7;
--card-icon-color: #8E8E93;
--card-text-color: #1C1C1E;
```

Dark mode equivalents also added.

## Files Changed

2. `ui/components/Chat/InputBar.tsx` - Restructured layout (context top, footer bottom)
3. `ui/components/Chat/InputBar.css` - New wrapper structure, hidden scrollbar
