I can't open pdf files with the built-in reader anymore. It will display an empty page (pdf-reader-like) saying page 0 of 0. Would've posted a screenshot if that was possible. :-
Is this a known issue? Haven't found a reference to it.

@leushino: fair enough, but a vision would still be nice. Is Opera going to be (eventually) a highly customizable browser that will also suit knowledgeable people? Or will Opera rely on extensions for any advanced feature that we used to have before?

It would help if the architect told a little bit more about what's going to be added to this new building in the future. It's bad enough that we've lost many things from the old house which were exactly the reason why we preferred that over the competition, but it's worse to not know whether it will be anything like the old house again. That will help us decide whether it's worth waiting or else decide that we can move on and find an alternative that suits us better.
