Added support for a dynamic 'Custom' theme button that appears when user settings diverge from predefined themes. Improved theme state management by tracking the active theme name in localStorage, updating button states, and refining the preview to better reflect customizations. Also updated the settings page layout and styles for better user experience and fixed the preview to always show the custom title.
Introduces seven new built-in themes (cyberpunk, midnight-rose, arctic-ice, cherry-blossom, cosmic-purple, emerald-dream, mocha-coffee, lavender-fields) with corresponding JSON files, updates the FEATURES documentation, and enhances the settings UI to display and select these themes. Also updates theme loading logic in theme-manager.js and improves the theme selector layout for better usability.
Introduces a full browser customization system with support for theme presets, live editing, import/export, and non-destructive design. Adds new documentation for customization, updates the features list, and implements a ThemeManager for loading and managing themes at the application level. Updates home and settings pages to support live theming and preview, and adds four built-in themes (default, forest, ocean, sunset).
Site history is now managed in localStorage for faster access and better cross-tab experience, with file sync for persistence. Added a dropdown for quick site history access in the address bar, updated settings page to display and manage site history from localStorage, and improved history recording logic in both main and renderer processes. Also added debug info and test data utilities for development.
