When I use the viewer pane I don't like it when the pane shows a thumbnail for a file that is no longer selected.
In DOpus 13 a setting has been added that will allow me to do that (by unchecking 'Leave file in viewer until another is selected'), which is nice.
But if I deselect a file by navigating to another folder, the thumbnail for the file I had selected remains in the viewer pane until I select a diferent file.
Could the viewer pane also be emptied when navigating to a diferent folder?
