Feature request: find unresolved conversations in pull requests

When a pull request has too many comments, older comments are hidden by default behind a “load more” link, with no respect for which conversations are marked as resolved or not. Therefore, when a PR is about to be merged, and there were many comments, it’s hard to know whether all conversations were resolved or not.

Compare to Azure DevOps, where the PR has a simply counter at the top saying “x/y conversations resolved”
