While I have your attention. A few thoughts on code reviews. It's be nice if 1) approvals somehow show up on the pull requests index page, 2) create a notification within GH, 3) send an email. Right now you have to go to the PR page itself to see approvals.
Edit: I saw an approval email notification on one PR, but not another.
+1 for seeing approvals visually on the pull request index page. I currently use a "Reviewed" label with my team, and unfortunately we still have to even with this feature.
We definitely want to get some way to surface reviews better across all PR's and/or projects. I've been bothered by that myself while we were building this. :)

Thanks!
