• Full Page Capture: Captures entire web pages, even if they require scrolling
• Manifest V3: Built using the latest Chrome Extension Manifest V3 API
• User-Friendly UI: Simple popup interface to start/stop capture and configure intervals
• Automatic Downloads: Screenshots are automatically saved to your downloads folder
