Markdown Comment Block is a free WordPress plugin designed to enhance the editing experience by allowing users to add comments that are only visible in the block editor. This feature enables users to jot down ideas, reminders, and notes without cluttering the front-end of their site. The plugin supports helpful block transforms, allowing for quick conversions between comments and standard text elements, which streamlines the editing process. Furthermore, a toolbar control is included for easily resolving comments, ensuring a clean workspace while drafting posts.

The plugin is designed with simplicity in mind, offering minimal rich text support to keep the focus on the content rather than formatting. Users can still apply basic text enhancements such as bolding, italicizing, and hyperlinking. Additionally, Markdown Comment Block is fully compatible with CSS variables, enabling users to customize the appearance of comments without needing extensive CSS knowledge. This functionality makes it a versatile tool for WordPress users looking to improve their writing workflow.
