Beta Forum post here.
They weren't kidding when they said there were performance improvements - startup time has pretty much dropped to maybe a quarter of what it was. Opera used to have a start up lag of about 4 seconds, but now I hit my hotkeys and there it is. Obviously I'm talking about a cold startup of the Opera application, opening pages is still instantaneous.
What's very encouraging as well is that they've enabled the personal bar by default again, yay :). Main bar was always a waste of space anyway.
It now probably takes me about 15 mins-half an hour to customise a clean install of Opera. I move over my search.ini, my cookies, my wand.dat, my address book. I enable smooth scrolling, switch on my ad-blocking style sheet. Move plug-ins, enable trusted protocols. And any number of small things like disabling the mail client, removing unwanted panels, identifying as Opera, blocking pop-ups, making it default browser, changing the hotkey, setting Outlook as mail client, applying Blue Button as my current skin of choice now that search boxes have issues...
There have a been a fuck load of previews so far, and I'm still sort of wondering how they're shaping up on the UI stuff, since the new search panel is sort of lame - not that the start page was that great either. The fine tweaking has been fantastic overall, but I wonder at the end result of all the UI work. I'm assuming that my java related crashes are just temporary.
Oh, and smooth scrolling is nicer again, which is good.
