Developer Launches UnScroll Extension to Reintroduce Pagination
An article describes how interface design — notably infinite scroll, algorithmic feeds and autoplay — has driven a rise in average daily screen time from ~1.2 hours in 1965 to over 7 hours in 2024. Citing historical product changes (Aza Raskin’s infinite scroll in 2006; algorithmic feeds, YouTube autoplay, TikTok loops) and platform metrics (NBC, Quartz), the author introduces UnScroll: a free, open-source Manifest V3 browser extension that restores numbered pagination to infinite-scrolling pages and offers features such as greyscale mode, autoplay disabling, mute notifications, hide like counts and text-only mode. The post explains technical details (scroll-container detection, SPA navigation hooks, closed Shadow DOM nav bar, MutationObserver-based autoplay blocking), lists supported sites, and links to the Chrome Web Store and GitHub repository.
The piece highlights how interface design patterns (infinite scroll, autoplay, algorithmic feeds) systematically increase attention and session metrics—factors that directly affect publishers' engagement, ad inventory value, and potential regulatory or UX countermeasures—but it reports a small independent open-source tool rather than a major platform policy or technical change.

- Aza Raskin invented infinite scroll in 2006; platforms like Twitter, Facebook, Pinterest, YouTube and TikTok adopted or popularized related engagement patterns.
- UnScroll is a free, open-source browser extension (Manifest V3 content script) that injects numbered pagination nav bars on infinitely-scrolling pages and offers features like greyscale, disable autoplay, mute notifications, hide like counts, and text-only mode.
- The extension claims compatibility with many sites (Reddit, Twitter/X, YouTube, Wikipedia, Gmail, ChatGPT, Gemini, LinkedIn, Facebook, Instagram) and publishes source code on GitHub.
- The article cites platform metric changes after switching to infinite scroll: NBC reported ~30% more mobile pageviews and Quartz saw ~50% more stories per session.

Local-only Chrome extension with 30+ tools
A developer published a privacy-first Chrome extension that bundles roughly 30 quick-action tools into a single draggable floating button and radial menu. The extension, called FloatDeck, runs entirely locally with no backend, no analytics, and zero network calls; the distributed bundle is around 50KB. It was implemented with vanilla JavaScript, Manifest V3 (MV3), and Shadow DOM to minimize size and avoid style collisions. The author (Mohan) posted a write-up on DEV Community on 2026-06-16 describing design decisions, trade-offs (radial menu vs. list), and noting the extension is free on the Chrome Web Store with no telemetry or account required.
Google Chrome Adds Vertical Tabs and Reading Mode
Google is rolling out new Chrome features: vertical tabs and an immersive Reading Mode. Vertical Tabs move the tab strip to a left-side column to show full page titles, improve visibility for many open tabs, and simplify tab-group management. The Reading Mode provides a full-page, distraction-free interface that hides visual elements such as videos, photos — and ads — while offering font, size and color options and text-to-speech. Chrome users can enable Reading Mode via a right-click menu on text-heavy pages. Google product managers Alex Tsu and Jess Carpenter framed vertical tabs as a multitasking improvement. The article notes the changes are available to all users and flags a possible downside for publishers because ads are hidden in Reading Mode. The piece also references other recent Chrome upgrades like in-browser PDF editing and automated AI browsing features.
Chrome adds vertical tabs and refreshed Reading Mode
Google announced that Chrome will offer an option to enable vertical tabs, moving tabs to the side of the window to expose full page titles and simplify tab-group management. The vertical-tabs option can be turned on from a right-click menu (“Show Tabs Vertically”) and will remain the user's default until changed; Google says there is no hard tab-count limit beyond hardware constraints. The update is rolling out gradually worldwide and is being released alongside a refreshed full‑page Reading Mode designed to reduce on‑screen clutter. Google framed the changes as responses to competition from modern browsers (e.g., Arc) and follows recent Chrome updates like Gemini AI integration, autofill improvements, and Split View.
