I’ve enabled user interface language settings. Since we’re all being Anglophone here it won’t make a big difference, except that it determines what language your web browser is prompted to use for its built-in spellcheck.
If this is a thing you care about, it may be worth checking your settings: (User icon), (cogwheel), Preferences, Interface, Interface Language. English options are “English” (UK) and “English (United States)”.
