Hi there,
I would like to suggest you a new improvement.
Why not adding a new layer of abstraction for commands or to make more
explicitly the commands?
For instance:
To merge a single file from one branch to another:
git checkout <branch_name> <path_to_file> --patch
would be like more readable human like this:
git merge <path_file> to <dst_branch>
It uses a more natural language.
Best regards.
