What it does
In Pull Request Review Dashboard users can easily move their pull requests (PR) to specific status: "In preparation" or "Ready for review".
Users will see how many PRs are currently in review and it's visible for reviewers how many PRs are pending for review.
When user creates a pull request, it automatically appears in status "In preparation". After all work is done, user moves PR into status "Ready for review".
Now reviewer steps in and moves PR to status "In review". Once PR is approved it has special badge. When PR is merged or rejected it moves automatically to status "Done".
If PR is not ready to be merged (f.e. there are some comments or suggestions), reviewer moves PR back in status "In preparation".
It's clear for PR owner that PR was reviewed and requires some work to do.
