 ## Best Practices for Effective Design Reviews
 
+### Using Comment Features Effectively
+
+To make your reviews more structured, Kanvas offers a number of tools inside the comment system itself. Use them to streamline collaboration and clarify your feedback.
+
+#### Use Color-Coded Comments
+
+Use color to visually categorize your comments:
+
+- 🔴 **Security** concerns
+- 🔵 **Scalability** or performance-related notes
+- 🟢 **UI/UX** feedback
+- 🟡 **Open questions** or suggestions
+
+This makes it easy for team members to scan and prioritize feedback based on type.
+
+#### Use Annotation Arrows 
+
+Link your comment to a specific part of the design using **annotation arrows**. This reduces ambiguity and ensures the context of your comment is crystal clear.
+
+#### Lock Important Comments
+
+Lock comments in place to keep them visible even as you continue working. This is helpful for feedback that should remain persistent throughout the review cycle.
+
+#### Group Related Comments
+
+Bundle multiple related comments using the **Group** feature. This keeps threads organized and easier to track, especially for complex designs with many parts.
+
 ### Resolving vs deleting comments
 
 Resolving a comment hides it from the canvas but keeps its history, so you can always revisit or reopen it later. Deleting a comment removes it entirely — including all threads and history — and cannot be undone.

 **What if two people act at the same time?**
 
 If someone resolves a comment while you're still typing in it, the comment will immediately close for both of you. You'll see a message letting you know that the thread was resolved.
