I tried DDG for little more than a week about a year a go and it made me realize how much I use the search suggestion feature in Chrome.
The lack of that feature using DDG really annoyed me. Often I don't know the exact spelling of the thing I'm looking for or the best way to phrase my question (English being my third language), and the suggestions I get in chrome just by typing a few letters in the address bar is really great. And often times I'm just looking for how to spell a word and with the suggestions I don't even have to leave the page I'm on.
