  🌐 English Version (For Global Users)
  
  NotebookLM Enhancer: LaTeX Export, Chat Timeline, Prompt Vault & Message Management.
  
  NLM Enhancer is an unofficial, open-source productivity extension designed specifically for researchers, students, and professionals using Google's NotebookLM. It perfectly solves the broken layouts and garbled text issues when exporting complex math from NotebookLM to Microsoft Word or Markdown.
  
  🚀 What's New in v1.3.2 (Major Update)
  
  - Formula Engine 2.0 (Word Optimized): Completely rebuilt the MathML translation pipeline. Fixed garbled text for overline symbols and restored precision for higher-order derivatives. Cleaned up redundant XML tags and invisible characters so exported formulas are much easier to edit natively in Word.
  - Prompt Vault & Question History: Your new productivity powerhouse. Save, search, and manage your most-used prompts with JSON import/export. Automatically track and 1-click re-insert past questions to keep your research workflow seamless.
  - Smart Stash & Unified UI: Added dynamic inline title editing for Stash exports that automatically syncs to your Markdown filenames. All panels (Vault, History, Cart) now feature a unified, responsive design with smart mutual exclusion to keep your workspace focused.
  
  🌟 Core Features:
  
  - Perfect Math Extraction: Seamlessly copy complex formulas into standard LaTeX or MathML. Say goodbye to missing characters when pasting into Word/MathType.
  - 1-Click Word & Markdown Export: Export entire conversations into clean .md or .doc files. Formulas, bold text, and lists are perfectly preserved.
  - Prompt Vault & History: Manage your research workflow with a professional prompt library and automatic question tracking.
  - Stash Cart & Precision Deletion: Stash important responses across different chats and use the "Pruning Mode" to pixel-perfectly remove unwanted content before exporting.
  - Timeline Navigation: A sleek sidebar timeline allows you to preview and jump to specific questions in long chats instantly.
  
  🔒 Privacy & Security (Zero Data Collection):
  This extension operates 100% locally. It contains ZERO external network requests, collects NO user data, and requires NO additional permissions in this update. Your notes and chats remain strictly between your browser and Google's servers.
  
  💻 Open Source:
  Fully open-source on GitHub: https://github.com/komazhou/NLM-Enhancer
  (Disclaimer: This extension is built by an independent developer and is not affiliated with, endorsed by, or sponsored by Google or NotebookLM.)
