  ChatGPT Message Cleaner is a lightweight browser extension designed for people who use ChatGPT frequently. When conversations become very long, the page may become sluggish, slow to load, or less smooth to scroll. This tool helps organize older content on the current page while keeping more recent messages visible, reducing page load and improving responsiveness.
  
  You can choose between two cleanup modes:
  - Hide mode: Temporarily hide older messages and restore them later when needed
  - Remove mode: Remove older messages from the current page to reduce on-screen content load
  
  Features:
  - Load protection: Automatically pauses when the page or system is busy
  - Idle processing: Runs during browser idle time with dynamic batch sizing
  - Speed control: Adjusts pacing automatically based on actual processing time
  - Multi-language support: English / Traditional Chinese / Simplified Chinese
  
  This extension runs entirely locally in your browser. It does not collect, track, or upload any data. It does not modify your account data or cloud conversation history. It only processes content currently displayed on the page. The source code is publicly available for inspection.
