I am currently evaluating Opus and am creating my first saved layout. The preview window does not show the new lister image, should it? The only thing displayed in the preview window is a white square somewhat shorter in width than the preview window itself. Thanks for any info...
That white square represents the lister window. The preview area is so you can see how many windows the layout will open along with their size and placement. You don't see what the actual windows themselves will look like.
e.g. This layout will open three listers on my left monitor (two small ones at the top and one wide one below) and another tall and thin lister on my right monitor:
