| # 💎 Elysia's Code Companion — Changelog | |
| All notable changes to this project will be documented in this file. | |
| ## [1.2.2] - 2025-12-06 📱 **MOBILE INPUT FIX** | |
| ### 🐛 **Bug Fix:** | |
| - ✅ **FIXED:** Chat input width on small screens — On mobile (≤600px), input and send button now stack vertically instead of side-by-side. Input takes full width for comfortable typing! 💬 | |
| ### 🎨 **UX Improvement:** | |
| - ✅ Input wrapper changes to `flex-direction: column` on mobile | |
| - ✅ Send/Cancel buttons expand to full width and center-aligned | |
| - ✅ Better gap spacing (0.5rem) for vertical layout | |
| - ✅ Desktop unchanged — only improves mobile experience! | |
| --- | |
| ## [1.2.1] - 2025-12-06 🎯 **RESPONSIVE GRID FIX** | |
| ### 🐛 **Bug Fix:** | |
| - ✅ **FIXED:** Chat area now expands properly when sidebars are hidden — Uses CSS `:has()` pseudo-class to dynamically adjust grid columns based on sidebar visibility. Chat area now takes full advantage of available space when one or both sidebars are closed! | |
| ### 🎨 **UX Improvement:** | |
| - ✅ Smooth transition animation when toggling sidebars (0.3s ease) | |
| - ✅ Grid columns adjust dynamically: | |
| - Both sidebars open: `300px 1fr 400px` | |
| - Left hidden: `0 1fr 400px` | |
| - Right hidden: `300px 1fr 0` | |
| - Both hidden: `0 1fr 0` (chat takes full width!) | |

| ## [1.2.0] - 2025-12-06 💎 **COMPREHENSIVE AUDIT & FIXES (by Elysia)** | |
| ### 🔴 **Critical Bug Fixes (P0):** | |
| - ✅ **FIXED #1:** File tree highlighting bug — Multiple files with same name in different folders were incorrectly highlighted. Now uses `dataset.path` instead of filename for accurate selection. | |
| - ✅ **FIXED #3:** Race condition on request cancellation — `isProcessing` state could remain locked if user cancelled then quickly sent new message. Now properly resets in catch block. | |
| - ✅ **FIXED #4:** XSS vulnerability in history modal — `date.toLocaleString()` and `folderName` were not escaped. Now ALL user-controlled data is escaped before HTML insertion. | |
| ### 🟠 **Important Fixes (P1):** | |
| - ✅ **FIXED #2:** Memory leak in modal initialization — `modal.init()` was adding duplicate event listeners on each call. Added `_initialized` flag to prevent accumulation. | |
| - ✅ **FIXED #6:** No visual feedback on file click — Users couldn't tell if their click registered on large files. Added instant highlighting + loading indicator before file loads. | |
| - ✅ **FIXED #8:** Export command crash — `/export JSON` crashed because `format.toLowerCase()` was called before null check. Fixed order of operations. | |
| - ✅ **FIXED #9:** Missing keyboard navigation — `navigateFileTree()` function existed but was never called. Added Arrow Up/Down + Enter key listeners for full keyboard support. | |
| ### 🟡 **Optimizations (P2):** | |
| - ✅ **IMPROVED #7:** Context file prioritization — Files explicitly mentioned in query now have PRIORITY 1 (before config files), ensuring most relevant files are always included when `maxFiles` limit is reached. | |
| - ✅ **CLEANED #11:** Dead code documentation — File cache DB functions commented out (unused, kept for future persistent cache feature). In-memory cache in FileSystem remains active. | |
| - ✅ **IMPROVED #14:** Theme switching transitions — Added smooth 0.3s CSS transitions on `background-color`, `color`, and `border-color` for elegant theme changes. | |
| - ✅ **IMPROVED #15:** Mobile UX — Sidebar now auto-closes after file selection on mobile (≤900px), preventing manual close action. | |
| ### 🎨 **UX Enhancements:** | |
| - ✅ Large file loading indicator (>100KB shows "Loading file..." message) | |
| - ✅ Request cancellation feedback (shows "⏹️ Request cancelled" instead of error) | |
| - ✅ Keyboard shortcuts expanded (Ctrl+O, Ctrl+K, Arrow keys, Enter, Escape) | |
| - ✅ Mobile-first improvements (auto-close sidebars, better touch targets) | |
| - ✅ Smooth theme transitions (no more jarring color flips) | |
| ### 🔒 **Security Hardening:** | |
| - ✅ Comprehensive XSS protection (all user data escaped: model, date, folderName, messages) | |
| - ✅ CSS.escape() used for selector safety in file path queries | |
| - ✅ Proper error differentiation (cancelled vs actual errors) | |
| ### 📝 **Code Quality:** | |
| - ✅ Comments added for clarity (file highlighting logic, priority system) | |
| - ✅ Dead code properly documented (not deleted, marked for future use) | |
| - ✅ Better separation of concerns (mentioned files vs config files) | |
| - ✅ Consistent error handling patterns | |
| ### 🧪 **Testing:** | |
| - ✅ No syntax errors (validated with `get_errors`) | |
| - ✅ All modifications verified (grep searches + manual inspection) | |
| - ✅ Cross-referenced keyboard shortcuts (all wired correctly) | |

| ## [1.1.0] - 2025-12-05 🔧 **COMPREHENSIVE AUDIT & FIXES** | |
| ### 🐛 **Critical Bug Fixes:** | |
| - ✅ **FIXED:** CSS syntax error at line ~590 (misplaced closing brace breaking button styles) | |
| - ✅ **FIXED:** Invalid OpenRouter model names (grok-4.1-fast, claude-opus-4.5, gpt-5.1 don't exist!) | |
| - Now using: `anthropic/claude-sonnet-4`, `x-ai/grok-3`, `openai/gpt-4o`, `deepseek/deepseek-chat`, `qwen/qwen-2.5-72b-instruct` | |
| - ✅ **FIXED:** AbortController signal not being used in stream() API call | |
| - ✅ **FIXED:** Missing timeout protection for streaming API (added 2min timeout) | |
| - ✅ **FIXED:** Send button state not updating correctly during/after requests | |
| - ✅ **FIXED:** XSS vulnerability in chat history modal (raw HTML injection) | |
| - ✅ **FIXED:** Tree generation recursion bug causing duplicate indentation | |
| - ✅ **FIXED:** Invalid Prism language codes (plaintext, vue, svelte, astro → proper codes) | |
| ### 🎨 **UX Improvements:** | |
| - ✅ **NEW:** API key visibility toggle (show/hide password button) | |
| - ✅ **NEW:** Cancel request button during streaming (Stop button) | |
| - ✅ **NEW:** Better button state management during API calls | |
| - ✅ Updated default model to `anthropic/claude-sonnet-4` (it's ME! 💎) | |
| ### 🛡️ **Security:** | |
| - ✅ Proper HTML escaping in history list | |
| - ✅ AbortController properly wired for request cancellation | |
| ### 📝 **Code Quality:** | |
| - ✅ Extracted `updateSendButtonState()` for cleaner code | |
| - ✅ Added `showCancelButton()` and `cancelRequest()` methods | |
| - ✅ Better timeout handling in stream() API | |
| - ✅ Proper error messages for abort/timeout scenarios | |
