Instead of just getting auto fill as you type, it auto gives you the possible results right as you type them.
Most amazing OP of all time ever. It's actually a pretty cool little feature. Very handy for when you are struggling to search for something, and you are trying out keywords. I've used it twice successfully today to hunt down old things I couldn't find due to obscure keywords!
I'm glad there's an option to turn it off. I've not yet decided if I actually like it or not - I type rather quickly and the constantly updating page is a little distracting for me.
i guess its better for people who have no clue how to use google search properly. But i find it slightly annoying tbh.
