Since Google doesn't want to listen on their official boards, I post it here:

Because of the untweakable autocomplete behavior of Chrome's "Omnibox", I deactivated Chrome on my devices and use Opera instead.

Just because of that super-annoying omnibox... bye bye Chrome... Google: you should re-learn to listen

Has anyone else here done the same?

They won't listen here either.

What's "Omnibox" is it the same machine in 'person of interest '?

Yeah.
