Just got back from a trip to find out my Opera and Opera GX have no more instant search. Downgrading back to v.67 until the instant search function is back. It was the best feature the browser had to offer, imo, together with the conversions. Speaking of it, conversions were a great combination with instant-search.
Would like to give some more attention to: "fans that use our browser because of its unique features" = negligible. I really don't mind, but that's a dangerous turn, and dangerous words, for a software that has been doing great with niche public so far.
