Opera has a neat feature for its settings called Power User mode.  What is even neater is how you enable this mode.

1. Bring up the settings tab
2. Type in that old game code with your arrow keys Up Up Down Down Left Right Left Right
3. Then type B A to finish the code

Just to be clear the whole code is the arrow keys for direction followed by B and then A, you don’t need to hold shift down or anything.

Up Up Down Down Left Right Left Right B A

One of the really cool things you can do in power user mode is remove the search box from the Speed Dial page.  Personally I prefer Bing but right now you cannot change this box from Google.  So removing it gives me more immediate space in my Speed Dial.
