When you review a flow and have comments, a question about the flow, or like to leave feedback, you can use the Comments feature on your flow canvas.
☝️ The main difference between labels and comments is that labels are mainly used for documentation, while comments are used for feedback, questions, etc.
You can add a comment by using Cmd + Click (Ctrl + Click for Windows and Linux users) anywhere on the flow canvas or by using the "Add comment" button on the bottom right of the flow canvas:
The comments on the Flows tab work exactly the same as in the screen detail. You can add visual elements, use Markdown-formatted text, organize them using colors, and so on. It's also possible to view/hide comments with the 🐵 button at the bottom right of the flow canvas and filter them by their colors or status (open/mentioned/resolved.)

💁♀️ You can make a comment stick to a screen by creating a comment on the desired screen or by dragging a comment on the flow canvas onto the desired screen.
Where to comment: the screen or the flow?
In Zeplin, you can add comments on either an individual screen or a flow. We'd recommend following this simple principle:
If your question or feedback concerns an element or behavior within a screen, then add the comment on the screen, not the flow.
If your question or feedback is about the user journey itself, for example, how a screen connects to another screen, then add the comment on the flow.
