Suggestion in address bar

[Admini]

Yes, they changed request headers. Thanks for the tip!
There is a new parameter "gs_ri=chrome-ext-ansg". In older versions was "gs_ri=chrome-ext".
I replaced in chrome.dll 
chrome-ext-ansg -> chrome-ext
chrome-omni -> chrome
and now "smart suggestion" works perfect in Cent v1.5.7.18 and above  

It would be great if in new versions Cent Browser, this function will be the default!

Yes. The difference has been shown in https://chromium.googlesource.com/chromi...4438%5E%21.
chrome-ext-ansg: "ansg" represents "Answer in Suggestion", now Chromium removed EnableAnswersInSuggest related codes and make "Answer in Suggestion" default.
Google server will not send any direct links if chrome-ext-ansg header exists.

If you replace chrome-ext-ansg to chrome-ext, then you will not get direct answer in the omnibox like below.
   

So we can't remove chrome-ext-ansg in a hurry. It may need an option, or we should leave it as is.
