A non-interactive settings bar is a questionable implementation. If there's going to be a separate settings bar, we shouldn't be forced to open a separate settings window to change the settings.

Better would be

With all the icons clickable for quick toggling of settings, including the language settings. The tooltip should be enough to tell us what the setting is, and then if people need further clarification, they can choose to open the settings window, as PotatoTree suggested.
