Just a minor note, it would be helpful to say in the manual, that one needs to have the 'results' window open to see the 'dual' view mode (or maybe have the result window pop open when one clicks on the 'dual' button, for the dense people like me who don't get how to work it right away
That threw me for a loop for a while, not seeing the 2nd window in the dual mode, til I checked here to see if the subject was already posted.
Or maybe just have a separate window pop up for the dual viewer, so one can have both the dual and results together side by side (sure why not add another layer.. I might have to get myself a dual-headed display to be able to handle all the windows/views but that's ok
Glad to have more windows/views
