I got to say, I am back on opera on sl on an older mac I had and I got back recently (because after an os update safari kept crashing on start up) and I have to say I am starting to realize again what a great browser it is and why I d fallen in love with it way back when. Opera has to be the single most underappreciated piece of commercial software. It's a testament to what a great team they have that having incomparably less resources than pretty much everyone from the other big players they have managed to keep up the quality for so long. It's super stable, super fast, doesn't leak and makes safari 5 with its leaks look like a turd (not that it needed opera to look like one, but anyway). Kudos to the devs, and heads up to anyone to give it a try. Oh, and here's an idea for apple to steal, they are good at that with safari (speed dial from opera, reader from readability, integrated search from chrome, extensions from ff, separate processes per tab from chrome etc. etc.), a great feature the new opera has: Click on a tab and move it on top of another tab (the other tab turns a deeper shade of gray). Release click. Now both tabs are in a group with a little right arrow next to them and a frame around. Actually it's a right arrow and it shows only one tab, when you click it shows all the tabs in the group and becomes a left arrow, if you click it again it's back to a right arrow and one tab only showing. What a great way to group tabs together from related themes/activities then save space by concealing all but one of the tabs in the group. It's such a pleasure to see opera brings another of this little brilliant details to the browsing experience.
