Searching tricks for new Opera

I could learn to cohabit con the new Opera if I only could do this:

1: move the bar on the bottom of the page ( I can't stand with on the top )

2: resize the thumbs in speed dial

3: delete the icons on the right of the page: " Bookmarks " , " news "...

Someone knows some working tricks ?

Kill F4 in opera hotkeys and let searchbar have it.

 

And if you hate the Omnibox, is there any way to install the search box in Chrome/Opera?

 

Thank you, I'll try it.
