Gaaaah-- THANK you @WKen! This is exactly what I was looking for, and it works so well! I have one last question for you... As of now, it appears that I have to click the button to activate this each time I start up Directory Opus. Do you know if there's a way to pre-activate or automatically activate it, so I wouldn't have to do so manually? Although, if not, the fact that you've created this per my request is already more than I was expecting! I appreciate this big time.

Regarding my use-cases, I have Portrait Oriented monitors, so horizontal real-estate is in short supply!
Since I browse a mixture of images and other files regularly, it's such a hassle to toggle the Viewer Pane open and closed every time I need to glance at a picture or two.
But this, at least for me, is a game-changer! I've been hoping for the ability to auto open/close the Viewer Pane based on what's selected, for years. And finally, Directory Opus... and WKen, have saved me!
