Seasoned Opera users are going to be unfamiliar with the default user interface of 7.50p1 because it's simply much cleaner than before. We've gotten a lot of useful feedback. It's very likely that the default UI in 7.50 final will not please many Opera users, however they'll be able to customize Opera so that they'll have what they prefer back.
Most of the frustrations with 7.50p1 are bugs, nothing more and nothing less. We'll get those cleared up as soon as possible and get out a shiny, new version to all you Opera aficionados. I hope that all users will have an open mind with each preview version--as the user interface matures--and provide us with constructive criticism.
