Features

A new tab page that earns the screen.

Every surface is real glass — translucent, blurred, layered over a wallpaper you choose. No more empty Google homepage every time you open a tab.

01

16 widgets, fully swappable

Clock, weather, status, notes, calculator, world clocks, recently closed, sound visualizer, pomodoro, to-do, crypto, quote, stopwatch, dice, search, picture of the day. Open Control Center and swap any slot from a dropdown — settings persist across reloads.

02

Spotlight that searches everything

Press / to search the web, your bookmarks, your open tabs, and quick actions in one panel. Same shortcuts as macOS — including ⌘ K and ↑ ↓ Enter navigation.

03

Themes & wallpapers

Glass, Light, and OLED themes pair with twelve built-in wallpapers — or upload your own. Every form control, dock item, and overlay follows the active theme.

04

Real browser-audio visualizer

Capture audio from any tab — YouTube, Spotify, Apple Music — and watch it pulse in bars, mirror, wave, or radial form. Six color palettes baked in.

05

Dock with live favicons

Add any URL and the icon is fetched automatically. Optional manual override via emoji or image URL. Hover-magnified, just like the real thing.

06

Auto-update banner

The extension polls this site for new versions on every tab. When one drops, a quiet banner appears at the top with a one-click download — no surprise reloads, no telemetry.
