The New Tab
that actually works for you.
Speedtab replaces Chrome's blank New Tab with a dense, modular workspace — bookmarks, RSS feeds, and encrypted notes. 100% local, no account, no cloud.
A ground-up rewrite.
10% lighter. Infinitely deeper.
Speedtab 1.4.0 is a complete architectural reboot — same dense workspace, radically faster core, and a whole new tier of features on top.
Ground-up rewrite
Faster startup, minimal memory, zero external dependencies, brand-new architectural foundation.
10% lighter
More features, less weight. Radically optimized end-to-end — smaller install, snappier boot.
Infinite tab nesting
HTML notes now support interactive nested tab structures — tabs inside tabs, as deep as you want.
WCAG 2.1 AA accessibility
Fully keyboard-navigable (Arrow / Home / End / Enter / Space), screen-reader friendly, 100/100 Lighthouse.
Persistent window lifecycle
Floating notes remember position & size in IndexedDB — survive reloads and browser restarts.
Interactive weather popup
Click the temperature in the weather rail to open a detailed weekly forecast modal.
Smooth swipe gestures
Touch-friendly gesture navigation across your dashboard on any touch-enabled device.
Dedicated sorter surface
New sorter.html lets you rearrange your whole workspace without disturbing the live dashboard.
Isolated import / export
New import-export.html handles workspace transfers safely, away from your live nav state.
Polished onboarding
15 tailored help notes ship inside the Quick Start example workspace.

/// The complete feature list
Every piece of the puzzle, in one place.
The full Speedtab 1.5.0 capability breakdown — app shell, bookmarks, notes, feeds, widgets, capture, sync and maintenance.
App shell & workspace architecture
- Viewport-filling app shell with customizable multi-page navigation for workspaces or context categories.
- Drag-and-drop reordering for pages, modules, collections and individual items.
- Event-delegation core (YaiJS + YEH) on a single shared runtime — O(1) scaling, zero virtual DOM overhead.
- Full keyboard navigation and WCAG 2.1 AA support (Arrow, Home, End, Enter, Space).
- Global debounced header search with instant locate flow, absolute results layer and in-page highlight cues.
- Global wallpaper plus per-page background overrides, custom CSS background editor with live validation and a saved gradient archive.
- Per-module layout controls: auto, multi-column span, full-width, min-height, spacing and padding overrides.
- Shell width boundaries and widget rail placement (top or bottom).
Visual bookmarks module
- Visual tiles with custom favicons or uploaded preview images.
- Built-in CropperJS tool to crop uploads to the tile ratio before saving.
- Asset browser & favicon manager: pick from IndexedDB assets, upload your own, auto-repair low-contrast or transparent dark favicons.
- Per-module open behavior: current tab, new background tab or new foreground tab.
- Tile modes — Default (106×60), Quicklinks (48×48 favicon-first), Big Tiles (154×80), optional title-below layout.
- Tile-level custom background colors with transparency support.
Notes & interactive note engine
- HTML notes: sanitized rendering, asset-backed placeholder tokens, inline images.
- Live, fully interactive YaiTabs nested tab structures hosted directly inside note content.
- Attribute-driven style API (data-st-*) for sizing, spacing, flexbox, grid, borders, radius, shadows, typography and color — without inline style vulnerabilities.
- Preset macros to inject layout skeletons and component templates into the editor.
- Text, Links (raw URLs → clickable lists, prose → quote blocks) and Code notes with Highlight.js syntax highlighting.
- Crypt notes: AES-GCM + PBKDF2-SHA256 (310,000 iterations); passphrases never stored or cached.
- Editor surfaces: split view with live preview, Flying Config for deeply nested tab content, and a local quicknote scratchpad kept out of workspace exports.
- Floating window system — draggable, resizable, focus-stacked notes that persist position and size across reloads.
Feed reader module
- RSS/Atom reader deployable inside any page module grid.
- Add, validate and auto-discover hidden feed endpoints from plain website URLs.
- Source filtering, visible article limits, read/unread tracking and bulk mark actions.
- Archive manager to save articles locally with optional comments.
- Expanded reader view with adjustable reading column width.
- Real-time in-feed text filter and optional per-module auto-refresh while the tab is visible.
- Cross-origin fetching executed safely by the background service worker.
Widget rail & utility tools
- Modular widget rail above or below your workspace pages.
- Digital or analog clock, localized formatting, token helpers, custom sizing, alignment and per-part colors.
- Local-first stopwatch and multi-timer on a zero-churn real-DOM render loop.
- Weather: compact rail readout, location search, °C/°F toggle and a detailed weekly forecast modal.
- Remote sync status indicator with visual health feedback.
Context menu capture & inbox
- Right-click any page or text selection to “Append to Quicknote” without switching tabs.
- Live pending counter in the tab title for unfiled clips (e.g. INBOX [3] — Speedtab).
- Inbox manager drawer to review, edit, filter and file clips into specific bookmark or note modules.
Data ownership, storage & remote sync
- 100% local-first: state, module structures and binary assets in IndexedDB via Dexie.
- Checksum-verified JSON exports (speedtab-export-<checksum>.json).
- Identity-aware merge engine to move workspaces between profiles without duplicating records.
- Isolated import/export surface (import-export.html).
- Optional WebDAV sync: manual push, pull, remote comparison and status checks.
- Optional Google Drive sync via chrome.identity to your hidden app-data folder, with auto-push intervals and health verification.
Maintenance, sorter & localization
- Dedicated grid sorter (sorter.html) to reorganize page hierarchies, edit tab titles inline and cascade deletions.
- System cleanup manager to detect and clear orphaned records, unused assets and stale favicons.
- Native chrome.i18n internationalization.
- Full UI translations and localized example workspaces in English, German, Turkish and Hindi.
