@ShriviShine Vivaldi's interface is built as an additional layer on top of the Chromium code that is used to render pages. (This also has a small effect on performance).

Some parts of Chromium remain, e.g. if you go to chrome://settings/content/zoomLevels it will show the Chromium page, but display the redirect URL in the address bar.

This option is not yet available in the Settings dialog.
