That's actually a use case I've thought about. When review time came around, one of my past managers would compile statistics on everyone's reviews to see how much they've been participating.

Another feature I've thought about is "show me all of person X's reviews and comments across all repos". That would have been super useful when I was on promo panels to go through and see if a promo candidate's review comments were useful, constructive, kind, etc.

Thanks for the feedback. I really appreciate it!
