Smart TOC & Scroll

Smart TOC & Scroll adds lightweight reading navigation to long articles, blogs, and documentation pages. It gives you two navigation types for different reading contexts: - Standard TOC Panel: a full outline with active-section highlighting, quick heading jumps, and a compact Top action. - Barcode: a transparent progress rail for immersive long-form reading, with four title previews: - Wheel: headings move through a fixed observation window. - Spotlight: a compact five-row context window keeps the current heading readable without crowding the article. - GPT: the idle rail stays minimal, then hover opens a bordered, scrollable panel containing the complete outline. - SSPAI: slim vertical ticks stay anchored beside the content or viewport edge; hover reveals the outline without moving the ticks, and a pin keeps it open. Key features: - Builds a clean outline from page headings - Highlights the section you are currently reading - Smoothly jumps to headings and back to the top - Adapts gently to light and dark page surfaces - Keeps the progress rail transparent and low-intrusion - Avoids duplicate TOC or back-to-top widgets when a page already provides them - Supports dynamic pages and single-page app updates - Runs page analysis locally in your browser Built for readers who want a clear sense of place without adding clutter to every page. Smart TOC & Scroll provides lightweight reading navigation for long articles, blogs, and documentation sites. It offers two navigation types: - Standard TOC Panel: displays a complete outline, highlights the current section, jumps quickly to headings, and provides a compact Top action. - Barcode: represents long-form structure with transparent edge markers and offers four heading previews: - Wheel: headings slide through a fixed observation window. - Spotlight: a compact context of two items above and below the current item reduces obstruction from dense text. - GPT: stays as a simple barcode by default; hovering opens a complete scrollable heading panel with a background and border. - SSPAI: slim vertical ticks stay fixed beside the content or screen edge and do not move sideways on hover; a pin fixes or releases the complete outline.
