I was thinking about how Lightroom works. In LR classic there is a toggle for a second screen (F11). And there's even an option on what to show on that 2nd screen (loupe, library, ...) .
In Dopus sometimes it's a bit the same. Mostly I want the preview to sit next to (or below) the folder as it is for now. But in some cases it would be nice to have the whole "screen real estate" of my 2nd or 3rd monitor showing what's going on in the folder (and also having it to react on the fileselection in the folder).
Just a suggestion for what I would think will not be a minor workaround.
