cubigato GmbH has released the terminal project tree-style-terminal as Open Source under the GPL-3.0 license. The project is now available on GitHub and is available to the developer community.

What is tree-style-terminal?

tree-style-terminal is a modern Python/GTK terminal application that replaces the traditional tab system with hierarchical tree navigation. Inspired by the popular tree-style-tabs add-on for Firefox, it enables the organization of terminal sessions in an infinitely nestable tree structure.

Main Features

Tree-based Session Management: Terminal sessions are organized in a hierarchical tree structure
Collapsible Sidebar: The session navigator can be hidden to create maximum terminal space
Session Adoption: When a parent session is closed, child sessions are automatically adopted by the grandparent session
Modern GTK Interface: Native Wayland and X11 support with CSS theming
Light/Dark Themes: Switchable between light and dark themes

Development Status

The project is in active development. Core application functions, the session management system, tree-based sidebar, and full theming support are already implemented. Features like session persistence and advanced keyboard navigation are in progress.
