V1.0.1

V1.0.1

🎨 UI/UX Improvements

• Refined Two-Column Layout: The interface now features a sticky left panel for paths and settings, while the right panel handles files, progress, and results for better navigation.
• Overlay Compare as Default: The overlay comparison view is now the default mode for quicker visual verification.
• Smarter Notifications: All standard notifications now auto-dismiss after 5 seconds to reduce clutter, while completion toasts remain persistent until manually dismissed.
• Context-Aware Controls: Quality settings are now automatically disabled in lossless/resize-only modes, and Max Width is disabled in standard mode to prevent invalid configurations.
• Visual Polish: Placeholder text no longer wraps unexpectedly, and overall spacing has been improved for a cleaner look.
• Streamlined Workflow: The Cancel button is now hidden until compression actually starts, and "Include subfolders" is unchecked by default.

✨ New Features

• Enhanced Recent Folders Management: You can now remove individual recent folders via a per-item × button or clear the entire list at once.
• New API Endpoints: Added POST /api/recent/remove and POST /api/recent/clear for programmatic management of recent folder history.

🐛 Bug Fixes

• Fixed a formatting issue where duplicate "Fixed" headings appeared in the changelog.

🐛 Stability & Security

This release also includes numerous reliability and security improvements:

• Fixed path traversal vulnerabilities in file-serving endpoints.
• Fixed XSS vulnerabilities in file name rendering on preview and results pages.
• Eliminated a race condition that could reset application state during active optimization.
