GitHub for Windows now offers a feature that allows users to select specific lines or blocks of changes to include in a commit, enhancing the ability to make small, focused commits that are easier to review and discuss in complex codebases. This functionality mirrors the interactive staging capability available through the command line with git add -i or git add -p, enabling users to manage their changes more effectively by committing only the desired modifications and leaving others for further development. This update is particularly useful for maintaining clarity and organization when handling a mixed set of changes within a working directory.
