We have explored into helping MR reviewer to post a summary of his\her code review. The same could be considered for the MR author. Potential applications: 1. **Declutter**: when another review round happens we could send a single email to the author with a brief summary of all the changes instead of sending one email per review comment. 2. **Top level view**: group reviewer comments into topics and higher level ideas 3. **Focus**: sort topics by importance
