 Manage your comment history by clicking on the "View Comment History" button. This allows you to revisit past discussions and decisions, ensuring that important context is never lost.
 
+From the comment history panel, you can manage individual threads without leaving the review flow:

+- **Resolve comment threads** once a discussion is complete while keeping the thread available for future reference.
+- **Mute notifications** for a specific comment thread when you want to reduce email noise without changing your broader comment notification preferences.
+- **Delete individual comments** when they should be removed entirely instead of kept as part of the design's historical record.

+For most review workflows, resolving a comment is preferred over deleting it because resolution preserves context and lets you reopen the thread later if needed.

 ### 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.

 ### Be specific and actionable
 
 Provide specific feedback that the designer can act on. Vague comments can lead to misunderstandings and delays in the design process. Support your feedback with examples or references. This can help clarify your point and provide the designer with tangible suggestions for improvement.

+### Balance positive and constructive feedback
 
 Frame feedback in a constructive manner, focusing on how things can be improved rather than just pointing out flaws. Acknowledge what works well in the design before delving into areas that need improvement. This helps maintain a positive and collaborative atmosphere.
