The Spellcheck Toggler plugin provides greater control over Obsidian's spellcheck behavior. It allows users to toggle spellcheck for specific types of content, such as internal and external links, as well as HTML comments. This plugin is particularly useful for those who find the red underline for spellcheck distracting, especially when working with links or code. By customizing the plugin settings, users can choose when to enable or disable spellcheck on different elements, improving their editing experience. The plugin is also open to feature requests, allowing users to suggest additional content types to toggle spellcheck for.
