Yes I know, but if I'm not at my own workstation I have to remember to change it. I'd like to go to duckduckgo.co.uk and have it immediately default to UK search - the same way Google.com does based on my IP.
Also, some users don't like that country level redirect and prefer the .com.
One solution, which does require a couple of steps is to use our Cloud save & save your settings anonymously in the cloud.
At the bottom of the settings page (https://duckduckgo.com/settings.html), you can enable cloud save, there is also a FAQ.
