Well, Opera’s at 10.51 now and it’s pretty sweet, except I have a few complaints.
1) Ctrl-z doesn’t work on the Speed Dial for reopening the last tab. I set up the ctrl-shift-t shortcut to ctrl-z to take care of that.
2) Opera 10.50 was extremely slow behind the proxy at work. I had to make a change to the config, but the average user would just switch to a different browser. It makes me sad because I love Opera.
3) Search bar gets squished when I put my Delicious bookmark next to it. Still have to report that.
Other than that, I love the update! Especially all the CSS support!
