kile doesn't open okular

Kile has some non-sense DocumenViewer side-view which simply doesn't work well on a laptop screen. And I really prefer all the functionality of Okular. So I tried for a long time to open Okular on PdfView, but to no avail. Here's how it works: Settings->Configure Kile, Tools->Build->ViewPDF. There you should select Okular instead of DocumentView. Yay.
Also don't forget that you should disable Live Preview (in Settings->Kile) and in: Tools->View (you should have PDFLatex->PDF(Okular)).
