Process Transparency Logic

The transparency system helps identify process importance:

• System/Kernel: Highly transparent (20-30%) - critical but background
• Services: Moderately transparent (50-70%) - important but service-level
• Applications: Least transparent (90%) - direct user interaction

File Preview System

• HTML Files: Rendered using iframe with 10% CSS transform scale
• Script Files: Syntax-highlighted code preview with line numbers
• Config Files: Structured display with key-value highlighting
• Log Files: Real-time log tail with color coding

🔧 Configuration

WebTop can be configured through config.json:

{
  "webtop": {
    "transparency": {
      "system_processes": 0.3,
      "user_processes": 0.9
    },
    "preview": {
      "html_scale": 0.1,
      "thumbnail_size": {"width": 60, "height": 40}
    },
    "process_monitor": {
      "update_interval": 2000,
      "max_processes": 100
    }
  }
}
