Translation of the app & name of the app

You've already expressed it in https://github.com/a-b-street/ltn/issues/17 but I don't think you created a independent issue since. LTN is between two worlds: I think it is currently used by a few somewhat-experts but the tool can or at least should also be used by non-experts. And a barrier for them could be the language / lack of translation.
I don't think the effort is that big on the tech side. Since we're a few frenchmen users (rouelibre1, arhzel, denis, me), we could help you translate the tool quickly.

Another related topic is that the name LTN is not really good marketing / SEO wise 😅. A renaming to something like "Serene streets" (easy to write / pronounce / remember / translate / but not too common) would probably help when communicating about the tool. [There's also the question of living under the umbrella of A/B street git project.]

この issue では、アプリの翻訳と名前変更について扱います。まず、コードベース内に既存の国際化 (i18n) の設定がないか探します。おそらく 'locales' や 'translations' のようなディレクトリにあります。現在 UI 文字列がどのように管理されているかを確認します。名前変更については、コード、ドキュメント、設定ファイル内で 'LTN' の出現箇所を検索します。'Done' は、アプリが複数の言語をサポートし、古い名前へのすべての参照が更新されていることを意味します。これは横断的な変更です。
