Cinnamon is a desktop environment interface for Linux operating systems. It provides a visual layout and user interface for managing windows and applications, focusing on desktop workflow management.
The project enables Linux GUI customization, allowing the look and feel of the environment to be modified. It includes a window management system to handle the placement and behavior of application windows within the workspace.
The environment utilizes a JavaScript-based shell and a modular applet architecture for extensibility, while using CSS for component styling. The interface is built with the GTK toolkit and employs the Muffin window manager for compositing and window decorations.
