Having to turn something on, then having it take up screen space instead is a stupid way to have to workaround this ridiculous situation.
So far this is my biggest gripe with Opera. Maybe if it were as fast as it claims, but it's still just middle of the pack. I'm starting to see my dislike of Chrome fade as I use Opera more, especially as it's based on Chromium.
I don't remember who called Opera a major browser alternative to IE, but they are out of touch with reality. There are a lot of people who have never heard of Opera. Many more know Firefox and Chrome. Even on mobile devices I'm willing to bet that Dolphin is as known as Opera.
I've been using Opera since I want to say version 4. The last three versions you had to pay for. Four, five, and six? I don't remember the versions. Huge, and noticeable improvements over IE and Firefox. Not not very noticeable at all, other than the pain in the ass it is to save webpages in something like bookmarks. Some things are industry standards for a reason... they work, and they work well. This is not an improvement in speed, efficiency, or anything else.
