Opera GestureBox extension

For those who missing page UP and page DOWN or mouse gestures, miss no more.
Install Opera Mobile Labs build with extensions and GestureBox extension. As you can see from screenshoots it's powerful tool

Bonus
For white background and black text (disables background image as well) save this as user.css to /data/data/com.opera.browser.extensions/opera/styles/ (usable with Opera classic too):

Code:

---

* { background: white ! important; color: black !important } 
:link, :link * { color: #222222 !important } 
:visited, :visited * { color: #333333 !important }
