            The settings in this section severely change the way the Home
            Assistant frontend works and looks. It is very easy to forget that
            you made a setting here when you switch devices or user.
            <p>
              Do not report any issues to Home Assistant before clearing
              <b>EVERY</b> setting here and thouroghly clearing all your browser
              caches. Failure to do so means you risk wasting a lot of peoples
              time, and you will be severly and rightfully ridiculed.
            </p>

          <p>
            Settings below are applied by first match. I.e. if a matching User
            setting exists, it will be applied. Otherwise any matching Browser
            setting and otherwise the GLOBAL setting if that differs from
            DEFAULT.
