In a productivity-focused workflow, where committing logical changes can be challenging, GitHub for Mac offers a solution by allowing users to select specific parts of their changes for commits. This tool provides flexibility by enabling users to commit selected lines or blocks of code rather than entire files, enhancing the efficiency of version control. Users can easily click on line numbers to select individual lines or hover and click on the right side of line numbers to commit entire blocks of changes. The feature supports both line-by-line and block-by-block selection, enabling users to manage their commits more effectively by committing selected changes and reserving others for future commits.
