# Enhanced Two-Column Layout - Picture Generator Tab (Final Version)

## Overview
Enhanced the Picture Generator Tab's Project Properties panel with an optimized two-column layout to maximize space usage, improve user experience, and ensure perfect button text visibility with proper scroll bar functionality.

## Final Optimized Layout

2. **template.jpg** file with Browse and Open buttons (same line)  
3. **Email Attachment** checkbox control (same line)
4. **File Management Buttons** on same line: [Add Files] [Add Folder] [Open] - **Full text visibility** ✅

### Right Column Content (Optimized width):
1. **Additional Files** list widget with **proper scroll bars** (horizontal & vertical) ✅

### User Help Section:
- **Increased height** from 200px to 300px for much better text readability

## Latest Fixes Applied
