Sublime Text plugins offer a range of benefits for full stack developers. They can significantly enhance productivity by automating repetitive tasks, providing shortcuts, and offering advanced features not available in the base editor. For instance, plugins like Emmet can speed up HTML/CSS coding, while GitGutter can show git diff information right in the editor. They can also improve code readability and debugging, with plugins like SublimeLinter providing real-time linting and BracketHighlighter enhancing bracket and tag visibility.
