The Comments plugin introduces a lightweight comment system that enables collaborative note-taking through inline callouts. Comments follow a structured format with author name and date, and can be quickly added via command or managed through a side panel. This dedicated view displays all comments in the current note and allows users to navigate to, reply to, or delete comments with simple clicks. Comments remain hidden in Reading mode and during exports like PDF, making them ideal for internal feedback or collaborative editing without cluttering the final output. It's particularly useful for teams or individuals reviewing notes together.
