For feature parity with Gerrit, we would need:
- A simple way (in Gerrit it's click a button, optionally edit the commit summary, click another button, done) to generate reverts of already-merged commits
- We would probably also want to be able to revert the entirety of a multi-commit change at once (Gerrit doesn't have multi-commit changes)
- A simple way to generate a cherry-pick of a commit (either merged or unmerged) submitted for branch A onto branch B
- A one-click way to rebase a commit B that is based on A onto A' (amended version of A)
- Optionally, a one-click way to rebase a commit onto latest master (or whatever branch it's supposed to be based on)
