FocusBar

Adds a static color bar overlay that highlights elements of a page as you scroll.

ELEVATE YOUR READING EXPERIENCE WITH FOCUSBAR FocusBar is a premium, modern Chrome extension designed to help you maintain deep focus. By highlighting your current line or paragraph and elegantly dimming the rest of the page, FocusBar eliminates distractions and reduces eye strain—now with full support for PDFs and framed research documents. Whether you are proofreading code, studying academic papers, or navigating dense spreadsheets, FocusBar provides a customizable "glassmorphic" overlay that moves with you. 🌟 KEY FEATURES (v2.3.0) • FOLLOW-CURSOR & CLICK-THROUGH MODES: Track your mouse effortlessly across dense tables and text (Alt+M), or enable Click-Through Mode (Alt+C) to select text, click links, and edit documents right through the highlighted reading bar. • SMART LINE & PARAGRAPH SNAP: Double-click the top or bottom edge of the bar to automatically snap its height to 1 line, 3 lines, or the exact paragraph underneath. • SMART-PINNING & PDF SUPPORT: FocusBar is container-aware. Pin the bar to specific scrolling sidebars, nested dashboards, or framed PDF viewers (iframes) on any research portal. • PER-SITE POSITION MEMORY: FocusBar automatically remembers your last position and height for every domain. Return to any documentation or academic paper and pick up exactly where you left off. • FOCUS MODE & SLIT MODE: Dim the entire page to highlight only the bar area. Toggle "Slit Mode" to invert the colors, creating a physical-style reading ruler on your screen. • SCREENSHOT & FILE EXPORT: Capture focused areas instantly. Standard click copies to clipboard; Shift+Click triggers an automatic hardware-accelerated download. • HARDWARE-SYNCED AUTO-SCROLL: Experience buttery-smooth, hardware-accelerated scrolling that matches your monitor's exact refresh rate for a jitter-free experience. • PROFILE PRESETS & RENAMING: Instantly swap between 3 saved configuration profiles. Click any profile label to rename it inline and stay organized. • SEAMLESS PAGE COMPATIBILITY: Works cleanly across any website layout without altering or breaking page styles. 🛠 GRANULAR CUSTOMIZATION • DUAL-EDGE RESIZING: Flexibly adjust your focus height by dragging either the top or bottom edge of the bar. • COLOR: Full HEX and Opacity control for your focus area. • SCROLL SPEED: Quadratic multiplier scaling with clickable numeric input override (0.10x to 5.0x). High-precision math flawlessly renders extremely slow reading speeds natively. • PREMIUM UX POLISH: Custom, high-contrast tooltips that never get clipped at screen edges and a new "hover-settle" delay that prevents accidental menu collapse during navigation. 📖 HOW TO USE 1. ACTIVATE: Click the extension icon or press Alt+Shift+F. 2. MOVE: Click and drag anywhere on the bar to position it. 3. RESIZE: Click and drag the top or bottom edge to change the focus height. 4. CUSTOMIZE: Hover over the bar to reveal the Glassmorphic FAB. Expand it to access all settings. 5. PROFILES: Click a slot to switch. Click the text label to rename your profile. 🔄 VERSION HISTORY v2.3.0: The "Reading Flow" Update • Added Follow-Cursor Mode (Alt+M) for smooth mouse-guided reading. • Added Click-Through Mode (Alt+C) to select text and click links directly inside the bar. • Added Smart Line & Paragraph Auto-Snap (double-click top or bottom bar edge). • Upgraded Popup Control Deck with instant profile switching, quick mode toggles, and live multi-tab synchronization. • Added hands-free reading shortcuts (Alt+Space, Alt+1/2/3) with smart input-field guards. v2.2.0: The "Context-Aware" Update • Added Multi-Frame Support for pinning inside iframes and PDF viewers. • Implemented Smart-Pinning: the bar now identifies and anchors to the specific scrollable container it is over (sidebars, dashboards, etc.). • Added Frame Guard to prevent UI injection in tiny advertisement frames. v2.1.0: The "Power User" Update • Added Per-Site Memory for position/height persistence per domain. • Implemented Shift+Click for direct Screenshot-to-File export. • Added Top-Edge resizing handle. • Overhauled tooltips and hover logic for a premium, flicker-free experience. • Added inline profile renaming. v2.0.2: Smooth Sub-Pixel Scrolling • Bypassed OS-level fractional pixel limits to allow flawless auto-scrolling at incredibly slow speeds (0.10x). v2.0.1: Improved Slider Sensitivity • Quadratic scaling curve for auto-scroll speed and live numeric speed display. v2.0.0: Complete Architecture Rewrite • Migrated to Vite/ES Modules, Shadow DOM isolation, and Reading Slit Mode. 🔒 PRIVACY & SECURITY FocusBar runs entirely on your device.
