Feedback: when I am reviewing a PR of a 3-PR stack (see attached screenshots) and scrolling down to the middle of the PR, there's no way to easily switch to another PR in the same stack to compare changes. I have to scroll back to the top of the web UI to pick another PR. Can you make the PR title at the left-top corner a clickable dropdown menu (I marked it by a red square in the screenshot 2) so I can navigate to another PR in the stack?

Would the Shift+Cmd+↑ shortcut work for what you're after? (Perhaps I'm misunderstanding)

Yes the shortcut brings me to the top of the UI, so I can select another PR. But I still think it would be easier to let me navigate to another PR in the stack by just clicking the title.

When I use the shortcut, it moves me between the PRs in a stack, it doesn't bring me to the top of the UI. Is that not what you're experiencing?

Oh I see. Yes it moves me between the PRs. It also brings me to the top so I misunderstood it. But anyways I think shortcut is not enough. No one can easily get it (how do I see all the shortcuts?). It needs to be supported directly on the UI.

You can hit Cmd+K to quickly access commands, or hit G then K to see a list of shortcuts!
