🚀 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)

💾 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.
