お断り

この記事では、プラグインの機能の詳細説明などには触れません。
あくまで「導入しているプラグインの一覧と、主要な操作方法のまとめ」を目的としています。

補足（lazygit の格納先と日本語化）

Lazygit 自体は TUI（プラグインではなく外部ツール）。macOS 既定の設定パスは ~/Library/Application Support/lazygit。

- コマンド例:

    mkdir -p ~/.config/lazygit
    ln -snf ~/.config/lazygit "~/Library/Application Support/lazygit"

日本語化は ~/.config/lazygit/config.yml に次を追記:
