What's the most underrated VS Code extension?

One of the most underrated VS Code extensions is the 'Error Lens' extension. It provides a more detailed and intuitive way of displaying errors and warnings directly in the code editor, making it easier to identify and fix issues. Another contender is 'TODO Highlight', which highlights TODO comments in code, making it easier to track tasks and reminders. Additionally, 'Code Spell Checker' is also underrated, as it helps catch typos and spelling mistakes in code and comments.
