The author says he reviews himself on a GitLab MR / GitHub PL, I rely on two things for this:
- git add -p, which also helps me split stuff in several commits if needed. It bothers me that it doesn't work for new files.
- git difftool dir-diff for changes with several commits
I like that it would work on any git hosting, and that it works locally. And that I can just amend my commits if I see something.
