o The most recent Speed Dial entries will always be used during the Opera Link synchronization process.
* Added Quick Find, an improved full text history search tool. Quick Find searches for text inside pages previously visited, not just the title and address. It is available from:

* New spatial navigation highlighting introduced, similar to the one used in Opera Mini 4 and the Wii browser.

o Keyboard shortcuts using Ctrl/Cmd+Shift no longer always open in a background tab.
o "Save Draft" shortcut Ctrl+S removed due to the new autosaving of drafts.
