📖 Aar318's Reading Mask Highlight: Focused, Accessible Reading

Keep your eyes anchored to one line at a time. Reading Mask Highlight adds a movable accessibility overlay to webpages, leaving a clear horizontal reading band between two colored guide lines while dimming the rest of the page. An optional local Simplified Reader can also turn compatible articles into a distraction-reduced reading view.

🚀 Getting Started
  1. Install the extension and pin it from your extension menu for easy access.
  2. Click the toolbar icon or press Alt+Shift+M to turn the reading mask on for the current tab.
  3. Move your pointer vertically on desktop, or drag anywhere inside the clear reading band on a touch device, to position it.
  4. Right-click the toolbar icon—or right-click/long-press the injected page control—to open settings, accessibility presets, and reading-session tools.
  5. Press Escape whenever you want to turn an active mask off.

✨ New Features (v1.5.0.1)
  • Kinetic Pause Persistence: Closing Simplified Reader no longer restarts a guide that the user paused.
  • True Live Toolbar Menus: The extension-icon menu now reads the active tab's current Reading Mask state directly, keeping mask status, injected-control visibility, domain access, opacity, and band size accurate.
  • Immediate Menu Refresh: Appearance, visibility, and domain changes update their right-click menu states without requiring a reload.
  • Consistent Support Menu: Ko-fi and Donate now appear together in the first native menu section above a separator and the Reading Mask actions.

⭐ Key Features
  • Per-Tab Reading Mask: Toggle the mask independently for each tab using the toolbar icon or Alt+Shift+M; the toolbar badge shows when it is active.
  • Clear Reading Band: Focus on a single horizontal region while customizable upper and lower masks dim surrounding page content.
  • Accessibility Presets: Apply coordinated dyslexia-friendly typography, spacing, high contrast, warm or cool tint, and reduced-motion settings to Simplified Reader.
  • Reading Session Tools: Use an optional timer, break reminders, progress marker, resume position, and one-click session restart.
  • Pointer, Touch, and Keyboard Control: Follow the pointer on desktop, drag the clear band on mobile, optionally switch to a dedicated grip-only mode, or adjust position with Arrow, Page Up/Down, Home, and End keys.
  • Simplified Reader: Open a private text-focused version of compatible article content while retaining reading-mask, preset, progress, and resume support.
  • Complete Appearance Controls: Adjust band height, guide thickness and colors, mask color and darkness, page-control position, visibility, and fade timing.
  • Responsive Mobile Design: Includes full-band dragging by default, optional grip-only control, larger touch targets, safe-area and orientation handling, native page scrolling, and layouts sized for smaller screens.
  • Injected Page Control: Toggle the mask directly from the webpage and open the complete settings panel with a right-click or touch long-press.
  • Toolbar Shortcuts: Access mask controls, settings, presets, domain management, appearance reset, and support links from the extension-icon menu.
  • Domain Rules: Run everywhere except a blocklist or only on an allowlist, with automatic subdomain matching and current-site controls.
  • Optional Page Control: Hide the injected control globally or on selected domains while continuing to use the toolbar and keyboard shortcut.
  • Accessibility Features: Provides visible focus states, keyboard-operable controls, descriptive labels, tooltips, isolated styling, and automatic print hiding.
  • Quick Mask Presets: Apply Compact, Standard, or Large reading bands and Light, Standard, or Dark mask styles.
  • Start-Enabled Option: Automatically activate the mask after supported page navigation when desired.
  • Dynamic-Page Recovery: Reattaches the overlay after client-rendered sites rebuild content while reducing checks in hidden tabs.

🔐 Permissions & Privacy
  • Storage: Saves appearance, behavior, accessibility presets, reader-session preferences, domain rules, onboarding state, and other settings locally in the browser.
  • Context Menus: Provides right-click toolbar shortcuts for toggling, settings, presets, domain controls, and support actions.
  • Site Access: Runs the reading overlay on webpages so it can dim page regions, follow pointer/touch movement, apply domain rules, and create Simplified Reader locally when requested.
  • Privacy: Settings, progress, resume positions, and page content remain on your device. The extension contains no analytics, tracking, accounts, remote code, advertising, or background network requests.

ℹ Notes
  • Simplified Reader appears only when the current page contains suitable article-style content.
  • Browser-protected pages and extension-store pages do not allow normal extension content-script access.
  • All reading-mask and extension controls are automatically hidden when printing.
