Ha I love that DDG changes the title of the window, so you can be on a different tab and still see the timer. Awesome. This is what I see: http://i.imgur.com/zHyPyYX.png Also it will say [Done!] and play an alarm. Very cool.
I actually do use DDG prolifically and have come to love all the widgets. I just think its silly for google to demand that you log in to use a glorified egg timer. Why do you need me to log in for that?
Presumably they do this because there are other widgets which require login and they haven't bothered to separate the two.
