Prevent perspective opening in new window

Sometime ago I configured a perspective to always open in a new window. I am now using the test flight vs 4 on my Mac and want to stop that behavior and cannot find the setting anywhere. Any ideas where it is?

In OmniFocus 3 (and earlier), this open in new tab/window option could be specified in the Perspective window on the Mac. In OmniFocus 4, the Perspective window doesn’t support editing of perspectives. It’s only used to reorder, star, and open perspectives.

I’m hoping that the open in new tab/window option will be added to the view options that are available through the toolbar. I emailed Omni with this request.

Got it. So any idea how to disable it if it is already activated? Or do I need to onstall of3 just to turn if off.
