How to have two subfolders in Dual Display?

It sounds like a newbie question, most probably it is.

If at all possible, I'd like to accomplish the following:
Explorer view, select 2 subfolders (in right window panel)
say:
D:\Folder1
D:\Folder2

Then... what action to take...(?)

in order to:

  • view the contents of both folders in Dual Display mode (within the same Opus session)
  • switch between images and explorer for both folders

this to compare/update the images in the folders more easily.

I believe F6 will only get a 2nd window pane of the existing window pane, i.e. not the subfolders.

Thanks

This would roughly be the idea, comparing folder-1 and folder-2
both thumbnail view.
