Reviewing large PRs in graphite is quite a chore. I understand some of the constraints that make it a hard problem to solve, and I've generally landed on an OK workflow. One minor annoyance that I hope can be fixed is this: I hover my mouse over the 'mark as viewed' checkbox. I approve the file. My screen scrolls (great!). I go to expand the next file by clicking its title bar (moving my mouse slightly left). Instead, I click on the 'Mark as Viewed' informational popover and my click is ignored. I have to move my mouse again to aim around the popup. If we could make the informational popover above the checkbox instead of to the left, you'd save me hundreds of dead clicks a week.

Thanks for the feedback! I can see the issue you mean -- the current Mark as viewed tooltip appears to the left of the checkbox, which can put it right in the path of the next click when you are moving quickly through a large PR. I’ve passed this along to the team as another signal on our existing PR page usability work.
