Islet

The notch Windows never had.

A Dynamic-Island-style pill at the top of your screen for music, Claude Code and Codex, notifications, battery, search and a dock of small tools. Free, open source, one installer.

[!TIP] Hover to open it, click anywhere else to close it. When nothing is happening Islet shrinks to a plain black pill with one dot.

The open notch, left to right: agent sessions → music → time and battery → tools.

✨ What's new

🐾 2.3: bring your own pet	Load any pet in the Codex Pets format. The pet talks in the closed pill, codes along with your agent, asks when it needs you and plants a flower after focus sessions.
📱 2.2: dock and Phone drop	A dock with Phone drop, Links, World clock, Clipboard, Notes, Timer, Shelf, Weather, Units, System and AI coding. Scan a QR code to move files between phone and PC over Wi-Fi.
🔎 Search	Alt+Space finds apps, files, folders, Wi-Fi and Bluetooth switches, settings, clipboard items and notes.
🍅 Focus tools	Pomodoro and stopwatch from the tray. Do Not Disturb turns on by itself during focus.
🔊 Volume, brightness and mic HUD	Level bars and clean icons in the notch; a muted mic gets its own red toast.
🌌 Black hole charger animation	Interstellar-style, when the charger goes in or out. Cinematic, Subtle or off.
🔄 2.1: installer and auto-update	A proper installer, a welcome screen that asks before changing anything, authenticated agent hooks and updates from GitHub Releases.

• Phone drop download links keep pointing at the file you picked, even if the shelf changes (a removed file now returns 404).
• A phone upload that is cut off no longer leaves a half-written file on the PC.
• The phone page reports network failures per file, carries on with the rest and lets you retry.
• Importing a pet from a .zip works again.
• The downloads page no longer overlaps its header on phones.

🐾 The dock and the pet

The dock row opens a tall view with every tool, each in its own panel:

Tool	What it does
📱 Phone drop	A temporary page on your local network: scan the QR code, send files to the shelf, take shelf files back. Stops after 10 minutes.
🔗 Links	Your saved links, one click away
🕒 World clock	Times in other cities
📋 Clipboard · 📝 Notes · 🗂️ Shelf	History with pins, quick notes, drag files in and out
⏱️ Timer	Timer, Pomodoro, stopwatch
🌤️ Weather	Next 6 hours and 5 days, humidity and wind
📐 Units · 📊 System · 🤖 AI coding	Converter, live PC stats, your agent sessions

The pet reacts to your PC. The first matching mood wins:

Mood	When
🤒 Sick	Battery under 20% and not charging
🚨 Alert	A pop-up arrived in the last 4 seconds
🙋 Ask	A Claude Code or Codex session needs you
🌱 Plant	A focus session just ended
🎧 Work	A focus or Pomodoro timer is running
💻 Code	An agent session is working
🎵 Dance	Something is playing
😴 Sleep / idle	Two quiet minutes / anything else

Settings → Choose a pet… loads a pet in the Codex Pets format (a .zip or its pet.json, with a sprite sheet of 192 × 208 frames). Use the cat switches back.
