GitSavvy is a full-featured Git plugin for Sublime Text, providing an extensive keyboard-driven interface for common Git operations. It includes a status dashboard, diff viewer, inline diff, commit view, log graph with interactive rebase, blame, branch/tag management, stash management, and integrations with GitHub and GitLab for pull/merge requests and remote operations. The architecture is built on a mixin-based command system, an asynchronous runtime for UI/worker thread management, and a reactive UI framework for dashboard views. It leverages custom Sublime Text syntax highlighting for Git-specific views and is highly configurable via settings. The codebase demonstrates strong engineering practices with well-structured modules, caching patterns, and extensive test coverage, though it is tightly coupled to the Sublime Text API and has some legacy dependencies (e.g., Python 3.8 requirement, deprecated `imp` module usage).
