@farhan One suggestion, if it’s easy to do, as you mentioned, we currently need to check out the first commit and then the second commit to compare the changes. I think it would be better to create two separate PRs one base PR with the first commit, and a second PR with the second commit. This would improve visibility into the code changes and likely reduce the review cycle, since some of the changes have already been reviewed and merged in edx-platform.
