Changing the layout

I just installed the eM Client and I saw in the video that you can set the e-mail up so that you have the folders on the left, the headers in the middle and the e-mail itself on the right - basically like in Outlook. However, I can’t figure out where to change it! Mine is set to folders on the left, header on the top, and the e-mail body at the bottom.
Could anyone help me, please?

Please go to your menu, View -> Layout -> Message on the right.
