For code snippets management in Linux Mint, I would recommend using a third-party application called "Gisto". It is an open-source cross-platform code snippet organizer that allows you to manage and share your code snippets with ease. It also supports syntax highlighting for different programming languages. You can download it from their website or install it via the terminal using the following command:What application replaces the Snippet application from Windows for Linux Mint?
