The Comments panel allows the reader of the process documentation to leave comments on diagrams and activities.
To view comments, click on the "Comments" button in the Diagram menu and the Comments panel will appear. To hide the comments, click on the "x" or unpin the panel.
To add a comment, just write your comment into the text area at the bottom of the Comments panel and click on the small paper plane to the right. The comment then appears in the area above.
To leave comments not on the diagram but on individual elements, simply select the desired element in the diagram.
To delete a comment, click on the trash bin next to the comment.
Note that comments are not deleted, they are terminated. This means that they will be visible if the current history timestamp is set accordingly.
