To the right of the features above, I saw one can save their settings with a password, to the "cloud". This seems to be that you can enter this password when using DuckDuckGo elsewhere for your settings to be set again (or in Private sessions, though you'd have to re-enter the password on a new session).
Are there any other subdomains worth knowing? I was only aware of the Lite version so far.
