  Smart Tab Suspender helps you save memory and improve browser performance by automatically suspending inactive tabs.
  
  🚀 KEY FEATURES:
  
  • One-Click Suspend - Instantly suspend any tab to free up memory
  • Auto-Suspend - Automatically suspend tabs after a customizable period of inactivity (5 min to 2 hours)
  • Smart Protection - Never suspend tabs playing audio/video, pinned tabs, or whitelisted sites
  • Memory Savings Dashboard - Track how much memory you've saved with detailed statistics and charts
  • Whitelist - Add your favorite sites to never be suspended
  • Keyboard Shortcut - Press Alt+Shift+S to quickly suspend the current tab
  • Form Data Protection - Preserves scroll position and form data when restoring tabs
  • Memory Alert - Get notified when system memory usage is high
  
  💾 WHY USE SMART TAB SUSPENDER?
  
  Each browser tab can use 50-150MB of memory. If you're a tab hoarder with dozens of tabs open, this can slow down your computer significantly. Smart Tab Suspender solves this by suspending tabs you're not using, freeing up memory instantly.
  
  ✨ HIGHLIGHTS:
  
  • Beautiful, modern interface
  • Lightweight and fast - won't slow down your browser
  • Privacy-focused - no data collection, everything stays local
  • Works offline
  • Free and open source
  
  Perfect for users who keep many tabs open but want to maintain browser performance.
