It is really smooth. I'm actually kind of impressed.
Yeah it is. I didn't expect that from Opera.
However, as I use it more and more, these are really annoying for me.
(1) Ctrl + 1-9 for tab switching <=== by default it is mapped to Speed Dial
(2) Ctrl + PageUp/PageDown for going to next/previous tab <== which I had to configure myself
(3) Can't access my bookmarks easily like Google Chrome. I have to focus into the Address Bar to show the Bookmarks and click again.
(4) Bookmarks NOT sortable (is it possible to sort Bookmarks?)
Do you guys have any other things that you don't like?
