App engineers have curated the following list of VCS improvements:

• Offers easily readable diffs.
  • Diff UI should be readable
  • Diffs should not be polluted with changes like rebase / merge cruft
• Renders markdown nicely (e.g. README)
• Allows flexibility in branching and commit methodology (related to above)
  • Support viewing discrete commits (i.e. doesn't require squashing)
  • Support squash methodology as well (This is preferred for Android)
• Readable conversation view
• Integrates well with GitHub
  • Able to merge pull requests in a way that allows them to be marked as “merged” and not “closed”
  • Ideally, one can work directly in GitHub and things “just work”
