@andrew84 : Yep, everyone has their own idea. One assumes the Opera design team is taking notes and will determine what changes, if any, are needed. The bigger elephant in the room are the untold scores of silent user actions revealed through telemetry. If that returns favorable results then the loud and proud enthusiast bark fest probably won't change the default presentation but may score a more transparent switch in settings.
BTW - how's that Vivaldi project going, ya know the one that has a switch for everything? Might be an option for those dissatisfied with the current state of affairs.
