This add-on installs a Git Client in Oxygen. It contributes multiple side-views, each one specialized for various Git operations. The main one is called the Git Staging view. Using the Git Client add-on, various Git operations can be performed, such as committing changes into the local repository, pushing/pulling changes to/from the remote repository, creating, checking out and deleting branches, showing the history of the repository resources, and more. The add-on also includes a built-in tool for comparing and merging changes.
