Cinnamon
Cinnamon is a free and open-source desktop environment for Linux-based operating systems, originally forked from GNOME Shell. It provides a traditional desktop layout with a panel, menu, and system tray, focusing on user-friendliness, customization, and performance. It is the default desktop environment for Linux Mint and is designed to be intuitive for users transitioning from Windows or macOS.
Developers should learn Cinnamon when working on or contributing to Linux Mint, as it is the default desktop environment and integrates deeply with the distribution. It is also useful for developers who prefer a stable, customizable, and resource-efficient desktop for their development workstations, especially if they value a classic desktop experience over more modern or minimalist alternatives. Knowledge of Cinnamon can aid in system administration, desktop application development, or contributing to open-source desktop projects.
