Kile ⇒ sidebar problem

[hodgestructure]

Hello,
I have installed kile 2.0.2 . When I open it, the sidebar ( symbols ) looks like

But on the screenshot, it loos like

http://kile.sourceforge.net/showscreenshot.php?id=5

The differences are :

(1) I have "open files" "files and projects" "structure" "symbols" "scripts" on the sidebar, but in the screenshot, there aren't
But there are some symbols.

(2) In the screenshot, the panel of symbols is maximal. But in my panel, there are many selections, like "delimiters" "greek" "special characters."...etc
So most of the time, I have to use the scroll to find the symbol I need.
I don't like my panel, the one in screenshot is better.

So how could I change my panel to be like in the screenshot ???
