How to fit diagram into current viewport?

I'd like to fit my diagram objects so that they fill the available space both horizontally and vertically. Now for some reason they stack up vertically and leave so much empty space on the two sides. I tried the ‘apply current layout’ and ‘fit content’ buttons, but none did what I wanted.

Is there any way to do that? Or should I request a feature?



I found what I was looking for in Context Menu (right mouse button menu) > Layout and Orientation menu items.
