Smart TOC & Scroll

Adaptive reading navigation for long articles: TOC, progress outline, hover preview, smart skip, and smooth scroll to top. 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 为长文、博客和文档站点提供轻量阅读导航。 它提供两种导航类型： - 标准目录面板：展示完整目录、当前章节高亮、快速标题跳转和紧凑的 Top 回顶操作。 - Barcode：以透明边缘刻度表达长文结构，并提供四种标题预览： - 滚轮：标题在固定观察窗中滑动。 - 聚光灯：以当前项上下各 2 项组成紧凑上下文，减少密集文字遮挡。 - GPT：平时保持纯条形码，悬停后展开带背景和边框的完整可滚动标题面板。 - 少数派：细竖刻度稳定停在正文外侧或屏幕边缘，悬停时刻度不横移；图钉可固定或释放完整大纲。 核心能力： - 根据页面标题自动生成清晰目录 - 高亮当前阅读章节 - 平滑跳转到标题或回到顶部 - 根据页面浅色 / 深色背景做克制自适应 - 阅读进度 rail 保持透明、低侵扰 - 页面已有目录或回顶控件时自动避让，减少重复控件 - 支持动态页面与单页应用内容更新 - 页面分析在浏览器本地完成 适合希望在不打断阅读的前提下，快速掌握长文结构和当前位置的用户。
