I'd like to display the big view of an image on the sencondary monitor - not the fullscreen, just the big view, because so I'm able to edit (and zoom...) the image.
But how to do this?
I've chosen the layout with the three columns folder-tree | thumbs | preview so that the preview is my complete second screen. But in this way I neither can edit the image nor zoom and so on. So I have to double-click the thumb to get the big view, but now the image is centered - one half on the left, one on the second screen

Is there a solution for my problem to use the one screen for browsing and the other for preview/zooming?
