A new --all flag has been added to the command-line interface, enabling users to generate activity stats across all branches in a repository instead of just the currently checked-out branch. By appending --all to the underlying git log query, the tool now provides a much more comprehensive view of repository activity over time. This makes tracking your overall project contribution history much easier, especially when juggling multiple active feature branches.
