I did the same thing and edited my own notes for use. I havent founf the tab increase either- But I did walk through the fields and have this to share-
in the browser type in "opera:config"
All these are under "user prefs"

Automatic Ram cache: checked
Cache Directory4: changed to my sd card location example "\storage card\cache"
First update delay: 0
smooth scrolling: Checked
tab increase: 7---( unable to find)
Turbo mode: checked

then i would set the cache size to 10mb in the settings menue" Opera -> Menu -> Advance"

I take no credit for this- thanks PKNY!

Hope this helps
