Features & Capabilities

Main Features

Automatically opens configured tabs on startup. If a tab with the desired URL is already open, it is reused and moved to the correct position instead of being duplicated.
For each tab, you can define:
- URL: The address to load.
- Pinned: Whether the tab should be pinned.
- Muted: Whether the tab should start muted.
- Focus: Which specific tab should have focus (be visible) after loading.
Optional "Close other tabs" setting which, if enabled, closes all tabs not present in your saved list, ensuring a clean workspace.
Import all currently open tabs in the current window with a single click to quickly create your initial configuration.
