What functionality does the "notes" icon provide on a shared document?

The "notes" icon on a shared document serves an essential purpose by enabling users to create visible comments. This functionality is crucial in collaborative settings, as it allows team members or stakeholders to provide feedback, ask questions, or add additional context directly related to specific parts of the document. These comments are visible to others who have access to the document, fostering communication and ensuring that all contributors are on the same page.

By using the notes feature, users can facilitate discussions around content without altering the original document. This is particularly useful in environments where multiple revisions or inputs are necessary, allowing for a more organized approach to managing feedback. Therefore, this capability enhances collaboration and improves the overall efficiency of working with shared documents.
