Open Tampermonkey → go to Installed Scripts → click the little pen icon (edit).
Press Ctrl+A → Backspace to wipe the old code.
Paste the new code → Ctrl+S to save.
Then refresh Khan Academy.
If it still doesn’t run, it’s other browser extensions interfering
Yo, There's a mistake in your code and it doesn't work properly, how can I fix it?

// ============================================
// PATCH NOTES - v7.0 (Community Edition)
// ============================================
//
// 🆕 NEW FEATURES:
// - Auto-Clear on URL Change: Menu automatically clears all answers when navigating to different pages/assignments
// - Auto-Clear on Lesson Change: Detects lesson/unit switches and clears menu automatically
// - URL monitoring system checks every 500ms for navigation changes
//
// 🔧 IMPROVEMENTS:
// - Better Chemistry Support: Added mhchem extension for KaTeX to properly render chemistry notation (e.g., \ce{} commands)
// - Enhanced Widget Detection: Improved checks for all possible data paths (assessmentItem, assessmentItemById, assessmentItemByProblemNumber)
// - Smarter Widget Filtering: Now properly skips widgets that aren't graded (filters out graded:false and static:true to avoid decoy data)
// - Improved Error Handling: Better fallback logic for expression widgets when answerForms doesn't exist
//
// 🐛 BUG FIXES:
// - Fixed issue where answers from pre-loaded future questions could appear
// - Fixed KaTeX rendering errors with throwOnError: false option
// - Fixed image URL extraction for radio choices with standard markdown image syntax
// - Fixed potential crashes from undefined/null answer content in radio widgets
//
// 📋 TECHNICAL CHANGES:
// - Added lastUrl and lastPageTitle tracking variables
// - Integrated setInterval() checker for URL and lesson title changes
// - Added comprehensive null/undefined checks in handleRadio()
// - Enhanced regex pattern for image URL extraction
// - Added mhchem script loading for chemistry notation
//
