Vivaldi's advanced settings
Well, these aren't Vivaldi settings, but Chromium settings. I agree it would be nice for people to know about them, but only if it's made clear that they are Chromium settings, and that they will, bit by bit, be replaced by Vivaldi settings that do the same thing, as these are written. Hence, one day a "chrome://" address may work, and with the next version, it may not - having been replaced by the equivalent Vivaldi function - and of course the faster this happens, the better, in my view.
Yes, I suspected that they weren't Vivaldi's settings when I mistakenly typed the URL with vivaldi:// instead of chrome:// . Oh, well, at least we can access them in the meantime, and if Vivaldi introduces its own equivalents, maybe they'll be even better.
Who knows, maybe someday Vivaldi will have its own independent rendering engine. Then I'll stop seeing Google keys in my registry.
